Abstract

This invention relates to compounds having the general formula: <IMAGE> in which: R1 represents a hydrogen atom or a (C1-4) alkyl radical, R2 represents a hydrogen atom, a (C1-4) alkyl radical, a (C2-4) alkenyl radical, a (C1-4) alkoxy-(C1-4) alkyl radical or a tetrahydrofuryl- or tetrahydropyranyl- (C1-4) alkyl radical, R3 represents a hydrogen atom or a (C1-4) alkyl radical, and R4 represents a hydrogen atom or a (C1-4) alkyl radical, and their pharmaceutically acceptable acid addition salts. These compounds have valuable bronchodilator properties.
