Procedure

2.5 g of 2-isopropylthio-4-methylsulfonyloxy-1,3-thiazole was dissolved in 10 ml of acetic acid. 2.9 ml of 35% aqueous hydrogen peroxide was added to the solution and the reaction was continued at 70° to 80° C. for 2 hours. The reaction mixture was poured into cold water and neutralized with 5% aqueous sodium hydroxide. The neutral solution was extracted by ethyl acetate and washed with saturated aqueous solution of common salt, followed by drying over anhydrous sodium sulfate to be concentrated to 2.5 g of a white crystal of the objective compound (yield: 88.7%).
