Reaction Steps

(6-Imidazol-1-ylpyridazin-3-yl)hydrazine (500 mg) were initially charged in a mixture of acetic acid (4 ml) and water (8 ml) with addition of sodium acetate (232 mg) at RT while stirring. Thereafter, the mixture was cooled to 0° C. and cyanogen bromide (330 mg) was introduced in portions. After stirring for 2.5 h, the mixture was left to stand overnight. After cooling to 0° C., the mixture was alkalized with 10 M sodium hydroxide solution and extracted repeatedly with EA. The combined EA phases were dried over sodium sulfate, filtered and concentrated. 66 mg of the title compound were isolated.
