反応手順
3-(2-Hydroxyethyl)-2-imino-6-trifluoromethoxybenzothiazoline may be prepared in the following manner: 2-amino-6-trifluoromethoxybenzothiazole (9.4 g) and 2-bromoethanol (10 g) in absolute ethanol (30 cc) are heated for 95 hours to boiling. The mixture is cooled to a temperature in the region of 20° C. The precipitate formed is filtered off and washed with ethyl ether (100 cc). 3-(2-Hydroxyethyl)-2-imino-6-trifluoromethoxybenzothiazoline hydrobromide (6.4 g), m.p. 219° C., is thereby obtained.
