Abstract

2-Aminothiazole is obtained by hydrolysing a 1 : 2 dihaloethyl acetate with water, cooling and mixing the solution with a solution containing thiourea, and heating. The hydrolysate in the case of dichloroethyl acetate is believed to contain chloroacetaldehyde, hydrochloric acid and acetic acid. The reaction mixture from the low temperature chlorination of vinyl acetate may be used for the 1 : 2 dichloroethyl acetate. Examples are given of the conversion of vinyl acetate to chloro addition product, followed by hydrolysis, followed by treatment with solutions containing thiourea and urea, including one obtained from cyanamide with H2S and aqueous ammonia, without isolation of any intermediate products, to give 2-aminothiazole.
