Abstract
Compounds of the formula: ##STR1## in which R.sub.1 represents a hydrogen atom or a (C.sub.1 -C.sub.4)alkyl group, R.sub.2 represents a hydrogen atom, a (C.sub.1 -C.sub.4)alkoxycarbonyl group, a carboxyl group, a sodium carboxylate group, a group --CH.sub.2 OR.sub.4, where R.sub.4 is a hydrogen atom or R.sub.4 is a (C.sub.1 -C.sub.4) alkyl or (C.sub.1 -C.sub.4) acyl group, a group --CONR.sub.5 R.sub.6, or a group --CN.sub.4 R.sub.5, where R.sub.5 is a hydrogen atom or a (C.sub.1 -C.sub.4)alkyl group and R.sub.6 is a hydrogen atom or a (C.sub.1 -C.sub.4)alkyl, hydroxyl or (C.sub.1 -C.sub.4) alkoxy or (C.sub.1 -C.sub.3) alkoxyphenyl group and R.sub.3 represents a (C.sub.1 -C.sub.4)alkyl group, and their acid addition salts are useful as synthetic intermediates.
