Participants

Reaction Conditions

Reaction Steps

A mixture of acetic anhydride (1.84 g) and formic acid (0.9 g) was heated at 50° C. for 0.5 hours with stirring. The solution was cooled at room temperature ant to the solution was added the 2-formylamino-4-(4-amino-phenylthiomethyl)thiazole (1.6 g). The mixture was stirred at room temperature for 6.5 hours and then the mixture was poured into ice-water. The precipitates were collected by filtration, washed with water and dried in vacuo to give 2-formylamino-4-(4-formylaminophenylthiomethyl)thiazole (1.7 g, yield: 96.7%).
