The invention relates to compounds of the formula in which: Y is --CH-- or --N--; R.sub.1 is hydrogen, a halogen or a CF.sub.3, (C.sub.1 -C.sub.4)alkyl or (C.sub.1 -C.sub.4)alkoxy group; R.sub.2 is a methyl or ethyl group; R.sub.3 and R.sub.4 are each hydrogen or a (C.sub.1 -C.sub.3)alkyl; and X is: (a) a (C.sub.1 -C.sub.6)alkyl, a (C.sub.1 -C.sub.6)alkoxy, a (C.sub.3 -C.sub.7)carboxyalkyl, a (C.sub.1 -C.sub.4)alkoxy-carbonyl(C.sub.1 -C.sub.6)alkyl, a (C.sub.3 -C.sub.7)carboxyalkoxy or a (C.sub.1 -C.sub.4)alkoxycarbonyl-(C.sub.1 -C.sub.6)alkoxy; (b) a radical selected from (C.sub.3 -C.sub.7)cycloalkyl, (C.sub.3 -C.sub.7)cycloalkoxy, (C.sub.3 -C.sub.7)-cycloalkylmethyl, (C.sub.3 -C.sub.7)cycloalkylamino and cyclohexenyl, it being possible for said radical to be substituted by a halogen, hydroxyl, (C.sub.1 -C.sub.4)-alkoxy, carboxyl, (C.sub.1 -C.sub.4)alkoxycarbonyl, amino or mono- or di-(C.sub.1 -C.sub.4)-alkylamino; or (c) a group selected from a phenyl, phenoxy, phenylamino, N-(C.sub.1 -C.sub.3)alkyl-phenylamino, phenylmethyl, phenylethyl, phenylcarbonyl, phenylthio, phenylsulfonyl, phenylsulfinyl and styryl, it being possible for said group to be monosubstituted or polysubstituted on the phenyl group by a halogen, CF.sub.3, (C.sub.1 -C.sub.4)alkyl, (C.sub.1 -C.sub.4)alkoxy, cyano, amino, mono- or di-(C.sub.1 -C.sub.4)alkyl-amino, (C.sub.1 -C.sub.4)acylamino, carboxyl, (C.sub.1 -C.sub.4)alkoxycarbonyl, aminocarbonyl, mono- or di-(C.sub.1 -C.sub.4)alkylaminocarbonyl, amino(C.sub.1 -C.sub.4)alkyl, hydroxy(C.sub.1 -C.sub.4)alkyl or halogeno(C.sub.1 -C.sub.4)alkyl; to a method of preparing them and to the pharmaceutical compositions containing them. These compounds have neurotrophic and neuroprotective activity.
