Abstract

1,187,597. Intermediates for methine dyes. KONISHIROKU PHOTO INDUSTRY CO. Ltd. 19 July, 1967 [28 July, 1966], No. 33271/67. Heading C2C. [Also in Divisions C4 and G2] 2,6 - Dimethyl - 3 - ethyl - 5 - chloro - benzoxazolium-p-toluene-sulphonate is prepared by heating ethyl p-toluene sulphonate with 2,6-dimethyl - 5 - chlorobenzoxazole. Anhydro - 2, 6 - dimethyl - 3 - (3<SP>1</SP> - sulphopropyl) - 5 - chlorobenzoxazolium hydroxide is prepared by heating 1,3-propane sultone and 2,6-dimethyl-5-chlorobenzoxazole. 2 - Anilinovinyl - 3 - ethyl - 5- chloro - 6 - methyl - benzoxazolium - p - toluene sulphonate is prepared by fusing 2,6-dimethyl-3- ethyl-5-chloro-benzoxazolium p-toluene sulphonate with diphenyl formamidine. 2-(2<SP>1</SP>-Anilino - 2<SP>1 </SP>- methyl - vinyl) - 3 - ethyl - 5 - chloro - benzoxazolium-toluenesulphonate is prepared by heating 2,6 - dimethyl - 5 - chloro - 3 - ethyl - benzoxazolium p-toluene sulphonate with isothioacetanilide. 2,6 - Dimethyl - 5 - chloro - benzoxazole is prepared by fusing at above 200‹ C. 5- chloro - 4 - methyl - 2 - hydroxy - acetanilide, prepared by reacting 4-chloro-6-amino-m-cresol with (CH 3 CO) 2 O.
