Participants

Reaction Steps

Methyl 2-amino-5-phenyl-1,3-thiazole-4-carboxylate (3 g) was dissolved in pyridine (30 ml), and then acetyl chloride (2.73 ml) was added dropwise to the solution at 0° C. under N2 atmosphere. The reaction mixture was stirred at r.t. for 1.5 hours. Water was added to the solution at 0° C. The precipitate was filtered in vacuo, and the solid was washed with ethyl ether to give methyl 2-(acetylamino)-5-phenyl-1,3-thiazole-4-carboxylate (2.37 g) as a pale brown solid.
