The temperature is from -30.degree. to +100.degree. C. and preferably from ambient temperature to 100.degree. C. The mole ratio can be from 1 to 10. After the possibly necessary conversion of the Ar' group into the Ar group, the compound obtained of general formula (XIII) is reacted with an activated compound of general formula (VII) or (XV) and the protective group Sch is split off by the addition of an alcohol, for example methanol or isopropanol, or of a fluoride salt, for example sodium fluoride, tetra-n-butylammonium fluoride or the like, in an organic solvent, for example tetrahydrofuran or diethyl ether. The splitting off of the protective group Sch can also take place with aqueous ammonia solution or with acid/water mixtures, for example acetic acid/water (2:1 v/v) or hydrogenolytically over palladium-on-charcoal. The temperatures used are from -20.degree. to +150.degree. C. and preferably from 0.degree. C. to ambient temperature. The mole ratios can be from 1 to 100.

The following Examples are given for the purpose of illustrating the present invention:

EXAMPLE 1
1-(3-Cyanoindol-4-yloxy)-3-[2-(3-nitroxybutanoylamino)-ethylamino]-propan-2-ol fumarate
4.2 g. 1-(3-cyanoindol-4-yloxy)-2,3-epoxypropane (see European patent specification No. 0,045,910) are suspended in 100 ml. n-butanol, mixed with 11.5 g. 2-(3-nitroxybutanoylamino)-ethylamine and stirred for 2 days at ambient temperature. After removal of the solvent, the residue is chromatographed on silica gel with methylene chloride/methanol (95:5 v/v) and methylene chloride/methanolic ammonia solution (95:5 v/v). From the appropriate fractions, after removal of the solvent, there are obtained 4.6 g. of base. By dissolving in methanol and adding the calculated amount of fumaric acid, there are obtained, after suction filtration, 3.9 g. (40% of theory) of the desired fumarate; m.p. 155.degree.-156.degree. C.

Stirring is continued for 2 hours at 0.degree. C. and the solution is then allowed to warm up to ambient temperature overnight. After removal of the solvent, the residue is taken up in 0.6 liters ethyl acetate and the solution is washed 3 times with 0.2 liter amounts of water. The organic phase is dried and evaporated.

The solution is filtered off with suction and evaporated. The oily residue (21.8 g.) is dissolved in 200 ml. boiling propan-2-ol and this solution is mixed with 9.6 g. oxalic acid in 100 ml. boiling propan-2-ol. The solution is allowed to cool and the precipitated crystals are filtered off with suction, washed with ethyl acetate and diethyl ether and dried. There are obtained 22.0 g. (70% of theory) 2-[(4-hydroxy-1-piperidino)-carbonylamino]-ethylamine oxalate (m.p. 173.degree.-175.degree. C.). 5.4 g. of this salt are introduced at -20.degree. C. into 14.4 ml. 100% nitric acid.

There remain 3.0 g. of an oily residue of 2-[(4-nitroxy-1-piperidino)-carbonylamino]-ethylamine.
Experimental Testing
The compounds claimed have beta-blocking as well as nitrate-like properties and can therefore be used as antianginal therapy (heart disorder characterized by attacks of pain where there is an insufficiency of oxygen).
At present pharmaceuticals are available either for their nitrate-like properties, e.g. nitroglycerin, isosorbide dinitrate, isosorbide-5-mononitrate, or for their beta-blocker properties, e.g. propanolol, pindolol. Combinations of these drugs are also used, but so far no compound is available which by its working principle incorporates both qualities. The invention provides compounds which, surprisingly, have nitrate-like as well as beta-blocking qualities in overlapping dosage ranges. Thus, a single compound can be used to treat two separate (but usually related in occurrence) ailments.
Since such substances have so far not been developed specifically, a method for screening the nitrate-like action is not known. It is for this reason that the following method was developed:
(a) to show denitration properties (which constitutes the working principle of all nitrates; see U. Abshagen in Handbook of Experimental Pharmacology, Vol. 76, 1985, Chapter 10.) the denitration rate was evaluated in relation to that of the known isosorbide dinitrate metabolite isosorbide-5-mononitrate (V.sub.rel). To that end, rats were killed under narcosis and their livers re-perfused 4 min with a corresponding concentrated equimolar (5.times.10.sup.-5 M/l) solution of isosorbide-5-mononitrate and the substances to be tested respectively (a blood sediment solution was pumped through the liver vessels) and the freed amount in NO.sub.2 determined in the perfusate (outflowing fluid). To have comparable conditions, the perfusion with isosorbide-5-mononitrate (standard substance) was administered as control at the second time as if it were an unknown substance (in this way a liver performance change under the test conditions can be recognized and accordingly allowed for).
High V.sub.rel -values show a fast denitration, low values a slow denitration.
(b) The .beta.-blocking effectiveness was shown by administering rabbits isoprenaline in an amount of 1 mcg/kg i.v. and determining the dose, which causes an inhibition of 50% of the increase of the frequency through isoprenaline (ID 50.sub.fcor =inhibition dose 50%).
