Abstract: Compounds of the formula: ##STR1## in which R.sub.1 represents a hydroxy group, a C.sub.1 -C.sub.4 alkoxy group or an amino group of general formula --NR.sub.4 R.sub.5 in which R.sub.4 and R.sub.5 each represent, independently of each other, a hydrogen atom, a straight or branched C.sub.1 -C.sub.4 alkyl group, an allyl group or a methoxyethyl group, or alternatively --NR.sub.4 R.sub.5 represents a heterocycle containing 3 to 6 carbon atoms,Y represents a thienyl group optionally substituted by an alkyl group, andX represents a hydrogen or halogen atom,are useful as anticonvulsants and auxiolytics.

Abstract: A compound which is a 2-aminopyrimidine-4-carboxamide derivative represented by general formula (I) ##STR1## in which m represents 2 or 3,n represents 2 or 3,R.sub.1 represents hydrogen or methyl, andX represents a substituent selected from the group consisting of hydrogen, fluorine, chlorine, methoxy, ethoxy, methyl and 1-methylethyl, with the proviso that more than one substituent X may be present in which case each X may be the same or different, or a pharmaceutically acceptable acid addition salt thereof.

Abstract: A benzazepine derivative which is a compound of formula (I): ##STR1## in which: each of m and n denotes the number 1, oreach of m and n denoted the number 2, orm denotes the number 3 and n denoted the number 1; andR denotes hydrogen or a group of formula --Z--R' in which Z denotes a --CO-- or --CH.sub.2 -- group and R' denotes a phenyl group which is unsubstituted or substituted with from one to three substituents selected from halogen atoms, linear or branch (C.sub.1 -C.sub.3) groups and linear or branched (C.sub.1 -C.sub.3) alkoxy groups,or a pharmacologically acceptable acid addition salt.
