Zusammenfassung:	1,192,048. Dyestuff intermediates. CIBA Ltd. 4 July, 1967 [4 July, 1966], No. 30766/67. Heading C2C. [Also in Division C4] In Example 1, N - ethyl - N - 2 - p - toluenesulphonyloxyethylaniline is prepared by reacting N - ethyl - N - 2 - hydroxyaniline with ptoluene sulphochloride, m.p. 63 to 64 C. In Example 4, 2-acetylamino-5-nitrophenol- 21 - methanesulphonyloryethyl ether is prepared by reacting 2 - acetylamino - 5 - nitrophenol - 21 - hydroxyethylether with methanesulphochloride. In Example 7, 4-(N-ethyl-N-21-methane-sulphonyl-oxyethyl) - amino - 2 - methylbenzylidenemalonitrile is prepared by reacting 4-(N-ethyl- N - 21 - hydroxyethyl) - amino - 2 - methylbenzylidenemalonitrile with methane-sulphochloride. In Example 8, 3-nitro-4-phenylaminobenzenesulphonic acid - 21- methanesulphonyloxyethylamide is prepared by reacting 3-nitro-4-phenylaminobenzene - sulphonic acid - 21- hydroxyethylamide with methanesulphochloride.
