Abstract

1425430 5 - Substituted 2 - aminophenols INSTITUT NATIONAL DE LA SANTE ET DE LA RECHERCHE MEDICALE 24 June 1974 [26 June 1973] 27953/74 Heading C2C A process for preparing 5-substituted 2- aminophenols comprises opening by alkaline hydrolysis the oxazoline ring of a benzo-oxazolinone correspondingly substituted in the 6- position. The invention also comprises compounds of the formula wherein R 1 represents a hydrogen atom, an unsubstituted or substituted C 1-6 alkyl group, an unsubstituted or substituted phenyl or benzyl group, or a thienyl group and R 2 represents a hydrogen atom or C 1-6 alkyl group with the proviso that when R 1 represents a methyl group. R 2 does not represent a hydrogen atom.
