Reaction Steps

To a solution of 3-aminodihydrofuran-2(3H)-one hydrobromide (5 g, 27.5 mmol) in DCM (50 mL) was added benzophenone imine (5 g, 27.5 mmol) and the reaction mixture was stirred at RT for 3 days. The reaction mixture was diluted with water and DCM, the organic layer was extracted, washed with aquous sodium bicarbonate, brine, dried over sodium sulfate and concentrated in vacuo to give 3-[(diphenylmethylene)amino]dihydrofuran-2(3H)-one as a thick colorless gel which crystallized to a white solid.
