Summary: | Compounds of the formula: wherein A stands for the radical -(CH2)2- which may bear one or two defined substituents; R1 stands for a (3-4C) alkyl or cyclopropyl radical, or a phenyl radical which may optionally bear one or two defined substituents, or a heteroaryl radical of five or six ring atoms which may optionally bear a (1-3C)alkyl substituent; R2 and R3 stand for hydrogen or a (1-2C)alkyl radical, or R2 stands for a (2-4C)alkylene radical which is linked to one of the carbon atoms forming the two-carbon-atom-backbone of A so as to form, together with the adjacent nitrogen atom, a pyrrolidinyl or piperidyl radical; and one of R4 and R5 stands for hydrogen, and the other stands for hydrogen, a halogen atom or a (1-3C)alkyl or (1-3C)alkoxy radical; and acid-addition salts thereof. Processes for the manufacture of said compounds. Pharmaceutical compositions comprising one of said compounds and a pharmaceutical diluent or carrier. The compounds are 5-hydroxytryptamine antagonists. |
