反应详情

To a solution of 1-phenyl-2-thiocyanato-ethanone (20 g, 113 mmol) in HOAc (100 mL) was added 50% aqueous H2SO4 (20 mL). The mixture was refluxed for 10 min. The mixture was poured into water. The solid formed was collected by filtration to give crude 4-phenyl-3H-thiazol-2-one (20 g) which was used for the next step without further purification.
