Procedure

In a 200 ml three-necked flask were placed 2.0 g of 2-aminothiazole and 5.6 g of methyl p-toluenesulfonate, and the mixture was stirred at 120° C. for 4 hours. After the resulting mixture was cooled to 60° C., 100 ml of acetone was added and the mixture was stirred for 1 hour. The precipitates were filtered under reduced pressure, washed with acetone, and dried at room temperature under reduced pressure.
