Abstract

1309196 Amino-phenols FUJI PHOTO FILM CO Ltd 21 Oct 1971 [23 Oct 1970] 49076/71 Heading C2C [Also in Division G2] 4 - Amino - 3 - methoxy - phenol hydrochloride is made by coupling diazotized sulphanilic acid with resorcinol monomethyl ether, heating the product with sodium hydrosulphite and forming the salt with hydrochloric acid. 4 - Amino - 3 : 5 - dimethoxyphenol, 4 - amino- 3 - methylphenol, 4 - amino - 3 : 5 - dimethylphenol and 4 - amino - 3 - ethoxyphenol hydrochlorides are similarly prepared using 3 : 5-dimethoxyphenol, m-cresol, 3 : 5-dimethylphenol or resorcinol monoethyl ether in place of resorcinol monomethyl ether. 4 - Ethylamino - 3 - methylphenol hydrochloride is made by reacting 4-amino-3-methyl phenol with an ethyl halide.
