- R.sub.1 is C.sub.1 -C.sub.7 alkyl; and
- Ar is a divalent fused ring system having two or three rings and at least one benzene nucleus, and optionally having one or two hetero ring atoms selected from the group consisting of N, O and S.
- 2. A compound as defined by claim 1, wherein R.sub.7 and R.sub.8, which can be the same or different, are each hydrogen, C.sub.1 -C.sub.7 alkyl, C.sub.3 -C.sub.12 cycloalkyl, phenyl or benzyl, or R.sub.7 and R.sub.8 are combined such that --NR.sub.7 R.sub.8 is morpholino, 1-pyrrolidinyl, 4benzyl-1-piperazinyl, perhydro-1,2,4-oxathiazin-4-yl, 1- or 4-piperazinyl, 4-methyl-1-piperazinyl, piperidino, hexamethyleneimino, 4-phenylpiperidino, 2-methyl-1-pyrazolidinyl, 1- or 2-pyrazolidinyl, 3-methyl-1-imidazolidinyl, 1- or 3-imidazolidinyl, 4-benzylpiperidino or 4-phenyl-1-piperazinyl.
- 3. A compound as defined by claim 1, wherein R.sub.1 is isopropyl or tert-butyl.
- 4. An oxalate salt of a compound as defined by claim 1.
- 5. A compound as defined by claim 1, wherein Ar is a radical of the formula ##STR304##
- 6. A compound as defined by claim 1, wherein Ar is a radical of the formula ##STR305##
- 7. The compound as defined by claim 1, said compound being a compound of the formula ##STR306## or a pharmaceutically acceptable acid addition salt thereof.
- 8. A method for eliciting a .beta.-adrenergic blocking response in a warm-blooded animal, which comprises administering to said animal an effective .beta.-adrenergic blocking amount of a compound of formula (I) as defined by claim 1, or a pharmaceutically acceptable acid addition salt thereof.
- 9. A pharmaceutical composition of matter, in unit dosage form, for use in eliciting a .beta.-adrenergic blocking response in a warm-blooded animal, said composition comprising, per dosage unit, an effective unit .beta.-adrenergic blocking amount of a compound of formula (I) as defined by claim 1 or a pharmaceutically acceptable acid addition salt thereof, and a non-toxic pharmaceutically acceptable carrier therefor.
- 10. A method for the treatment of glaucoma or for lowering intraocular pressure in a warm-blooded animal, which comprises administering to the eye or the eyes of said animal an effective intraocular pressure decreasing amount of a compound of formula (I) as defined by claim 1, or a pharmaceutically acceptable acid addition salt thereof.
- 11. An ophthalmic composition of matter, in unit dosage form, for use in the treatment of glaucoma or in the lowering of intraocular pressure in a warm-blooded animal, said composition comprising, per dosage unit, an effective unit intraocular pressure decreasing amount of a compound of formula (I) as defined by claim 1 or a pharmaceutically acceptable acid addition salt thereof, and a non-toxic ophthalmically acceptable carrier therefor.
