    摘要: A process for preparing a compound of the formula (I): ##STR1## in which, R.sup.1 and R.sup.2 each represents hydrogen or C.sub.1 -C.sub.6 alkyl, or R.sup.1 and R.sup.2 together with the nitrogen atom to which they are attached form a heterocycle; E represents methylene, sulfur, oxygen or imino group optionally substituted with C.sub.1 -C.sub.6 alkyl or aralkyl; ring A is aryl or heteroaryl ring, optionally substituted; R.sup.3 is hydrogen or C.sub.1 -C.sub.6 alkyl and R.sup.4 is hydrogen or R.sup.3 and R.sup.4 together represent a group of formula (IV):--(CR.sup.a R.sup.a).sub.m --C(.dbd.Y)-- (IV)(wherein R.sup.a and R.sup.a is C.sub.1 -C.sub.6 alkyl or hydrogen, up to a maximum of 3 alkyl groups, m is 1, 2, or 3, and Y is two hydrogens or oxygen); provided that when E represents a methylene group, then R.sup.3 is a C.sub.1 -C.sub.6 alkyl group or R.sup.3 and R.sup.4 together represent a group of the formula (IV), which comprises reacting an acid of the formula ##STR2## with an amine of the formula ##STR3##
