| abstract | 1,222,533. Naphthothiazolium salts. EASTMAN KODAK CO. 15 May, 1968 [29 May, 1967], No. 22974/68. Heading C2C. [Also in Divisions C4 and G2] Anhydro - 2 - methyl - 3 - (3 - sulphobutyl)- naphtho-[2,3-d]-thiazolium hydroxide is prepared by reacting 2-methyl naphtho-[2,3-d]- thiazole and 2,4 - butanesultone. 3 - Ethyl - 2- methyl naphtho - [2,3 - d]-thiazolium-p - toluene sulphonate is obtained similarly. The compounds obtained when reacted with #-anilino acroleinanil hydrochloride in acetic anhydride give 2 - (4 - acetanilido - 1,3 - butadienyl) - 3- ethyl - naphtho - [2,3 - d] - thiazolium - ptoluene sulphonate and anhydro-2-(4-acetanilido - 1,3 - butadienyl) - 3 - (3 - sulphobutyl)- naphtho-[2,3-d]-thiazolium. |
