실험 절차
To a solution of 2-amino-5-(4-aminophenylthio)thiazole (4.0 g) in a mixture of chloroform (140 ml) and N,N-dimethylformamide (20 ml) was dropwise added the solution of 3-chloroperbenzoic acid (4.65 g) in chloroform (50 ml) at 5° C. with stirring. The mixture was stirred at 5° C. for 4 hours. The precipitates were collected by filtration, washed with 10% aqueous sodium bicarbonate and water. The solid was dried in vacuo to give 2-amino-5-(4-aminophenylsulfinyl)thiazole (3.75 g, yield: 87.5%).
