A process for the preparation of new phenylglycine derivatives of the formula (* see formula I) where R is a hydrogen atom or a methyl group and R1 is a lower alkyl group that can optionally be substituted with one or more groups selected from hydroxy, lower alkoxy, carboxy, amino, mono- or di- (lower alkyl) amino, phenyl and phenoxy and any of these phenyl or phenoxy groups may be optionally substituted with one or more hydroxy, lower alkyl or lower alkoxy groups; or an alkynyl, alkenyl, or cycloalkyl group; excluding the case where R1 is a 4-hydroxy or 4-methoxy-alpha-carboxybenzyl group; and their pharmaceutically acceptable acid addition salts. |
