Abstract

The invention comprises compounds of general formula: <FORM:0951653/C2/1> wherein R1, R2, R4 and R5, which may be th same or different, are each hydrogen or an alkyl radical having a maximum of 4 carbon atoms, Ar is an aromatic radical having not more than 8 carbon atoms and R3 is O or NH (including, when only one of R1 and R2 is alkyl, isomers in which it is attached to the nitrogen atom next to the -CR3- group), together with their pharmaceutically acceptable acid addition salts formed with non-toxic acids; and a process for their preparation by reacting a compound of formula: <FORM:0951653/C2/2> in which X is lower carbalkoxy having a maximum of 5 carbon atoms (when R3 is O) or cyano (when R3 is NH), with a compound R1R2N-NH2, the reaction being carried out at elevated temperatures in the presence of a hydroxylated polar organic solvent having less than 6 carbon atoms when X is lower carbalkoxy and in the presence of a lower alcohol having a maximum of 4 carbon atoms when X is cyano. In examples Ar is phenyl, pyridyl, thienyl and phenyl substituted by methyl, amino, hydroxy, methoxy, chloro, fluoro or trifluoromethyl. Specification 951,655 is referred to.
