Abstract

1348366 Substituted amino phenols NISSO KAKO CO Ltd 3 Aug 1972 [22 Jan 1972] 36392/72 Heading C2C [Also in Divisions C4 and D2] In preparative Example 1 4-hydroxy-2- methyl - 4<SP>1</SP> ethoxydiphenylamine is prepared by reacting 4-amino-m-cresol hydrochloride with p-phenetidine at 180-200‹ C. in presence of zinc chloride. Similarly in preparative Example 2 4 - hydroxy - 2 - methyl - 2<SP>1</SP> - methoxydiphenylamine is prepared by reacting 4-aminom-cresol hydrochloride with o-anisidine.
