Procedure

In 50 ml of dichloromethane was dissolved 1 g of 2-(pyridin-3-yl)-4-phenylthiazole. Thereto was added 900 mg of m-chloroperbenzoic acid at room temperature. The mixture was stirred at the same temperature for 2 hours. The reaction mixture was washed with an aqueous sodium hydrogencarbonate solution and dried The solvent was removed by distillation. The residue was recrystallized from ethyl acetate to obtain 306 mg of 3-(4-phenylthiazol-2-yl) pyridine-N-oxide as a brown powder.
