[1223] To a suspension of 4-[2-[(trifluoroacetyl)amino]ethyl]-benzenesulfonyl chloride (10.0 g) in 1,2-dichloroethane (50 ml) were added successively 1,2-dimethoxybenzene (5.22 ml) and aluminum trichloride (6.34 g) and the mixture was refluxed for 18 hours. An additional portion of aluminum trichloride (8.45 g) was added and the mixture was refluxed for 7 hours. The mixture was quenched by addition of water (200 ml) and extracted with ethyl acetate (200 ml, 100 ml). The combined extracts were washed with brine (300 ml) and dried over magnesium sulfate. Filtration followed by evaporation gave a dark purple paste, which was chromatographed on silica gel (eluent: hexane/ethyl acetate) to give the coupling products. The products were dissolved in dichloromethane (100 ml). To the solution was added 1.0 M solution of boron tribromide (83 ml) at 0° C. and the mixture was warmed to room temperature. After stirring for 12 hours, the solvent was removed by evaporation. The residue was suspended in ethyl acetate (100 ml) and carefully basified with saturated aqueous sodium bicarbonate (150 ml) under cooling at 0° C. The aqueous layer was separated and extracted with ethyl acetate (50 ml). The combined organic layers were dried over magnesium sulfate, filtered, and evaporated to give a brown solid, which was chromatographed on silica gel (eluent: hexane/ethyl acetate) to give N-[2-[4-[(3,4-dihydroxyphenyl)sulfonyl]phenyl]ethyl]-2,2,2-trifluoroacetamide (5.29 g) as a light brown solid.

To this one was added ethyl bromodifluoroacetate (0.063 ml) and the mixture was stirred at room temperature for 6 days. The resulting mixture was poured into water and the aqueous mixture was extracted with ethyl acetate. The organic layer was washed with water, dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (hexane:ethyl acetate=3:1 to 2:1) to give tert-butyl N-[(R)-2-(3-chlorophenyl)-2-hydroxyethyl]-N-[2-[4-[[4-(difluoromethoxy)phenyl]sulfonyl]-phenyl]ethyl]carbamate (109 mg).

[1410] To a solution of ethyl (R)-6-[[4-[2-[N-benzyl-N-[2-(3-chlorophenyl)-2-hydroxyethyl]amino]ethyl]phenyl]sulfonyl]-nicotinate (93 mg) in ethyl acetate (3 ml) was added 4N hydrogen chloride in ethyl acetate (0.12 ml) at room temperature, and the mixture was evaporated under reduced pressure. A mixture of the residue and 10% palladium on activated carbon (50% wet, 185 mg) in a mixture of ethanol (0.9 ml) and chlorobenzene (2.1 ml) was stirred at room temperature in the presence of hydrogen at an atmospheric pressure for 37 hours. After the catalyst was filtered off, the filtrate was evaporated under reduced pressure. The residue was dissolved into a mixture of saturated aqueous sodium bicarbonate and ethyl acetate. After seperation, the organic layer was washed with brine, dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (chloroform:methanol=20:1 to 15:1) to give ethyl (R)-6-[[4-[2-[[2-(3-chlorophenyl)-2-hydroxyethyl]amino]-ethyl]phenyl]sulfonyl]nicotinate (33 mg).

A mixture of the residue and 10% palladium on activated carbon (50% wet, 0.28 g) in a mixture of ethanol (17 ml) and chlorobenzene (39 ml) was stirred at room temperature in the presence of hydrogen at an atmospheric pressure for 1.2 hours to give precipitates. To the reaction mixture was added ethanol to dissolve the precipitates. After removal of 10% palladium on activated carbon by filtration, the filtrate was evaporated under reduced pressure. The residue was dissolved into a mixture of saturated aqueous sodium bicarbonate and ethyl acetate. After separation, the organic layer was washed with brine, dried over magnesium sulfate and evaporated under reduced pressure.

EXAMPLE 156

[1874] Under nitrogen at room temperature, to a solution of 3-[[4-[2-[N-benzyl-N-[(2R)-2-(3-chlorophenyl)-2-hydroxyethyl]-amino]ethyl]phenyl]sulfonyl]phenol (210 mg) and β-propiolactone (40 μl) in tetrahydrofuran (2.5 ml) was added potassium tert-butoxide (50 mg) by portion, and the mixture was stirred at room temperature for 48 hours. To this one was added 3.95N hydrogen chloride in ethanol (1.5 ml), and the mixture was stirred for 12 hours. The resulting mixture was evaporated under reduced pressure. The residue was diluted with ethyl acetate and an aqueous solution of sodium hydroxide (1N). The organic layer was seperated, washed with brine, dried over magnesium sulfate and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (methanol/chloroform=1/30) to give ethyl 3-[3-[[4-[2-[N-benzyl-N-[2-(3-chlorophenyl)-2-hydroxyethyl]amino]ethyl]phenyl]sulfonyl]phenoxy]propanoate (105 mg) as a colorless oil.

[1881] To a mixture of (R)-[4-[[4-[2-[[2-(3-chlorophenyl)-2-hydroxyethyl]amino]ethyl]phenyl]sulfonyl]phenoxy]acetic acid (102 mg) in a mixture of tetrahydrofuran (20 ml) and water (8 ml) was added saturated aqueous sodium bicarbonate to be adjusted to about pH 8.5, and to this one was added 1-[[[(5-methyl-2-oxo-1,3-dioxol-4-yl)methoxy]carbonyl]oxy]-2,5-pyrrolidinedione (68 mg) in tetrahydrofuran (3 ml) controlling the pH at 8.5 at room temperature. The mixture was stirred at the same temperature for 3 hours. The resulting mixture was adjusted to pH 3 with 1N hydrochloric acid, and ethyl acetate was added. After seperation, the organic layer was dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residue was purified by thin layer silica gel chromatography (chloroform methanol=3:1) to give (R)-[4-[[4-[2-[N-[2-(3-chlorophenyl)-2-hydroxyethyl]-N-[[(5-methyl-2-oxo-1,3-dioxol-4-yl)methoxy]carbonyl]amino]ethyl]phenyl]sulfonyl]-phenoxy]acetic acid (86 mg).
