Reaction Steps

A solution of 2-amino-2',5-dichlorobenzophenone hydrochloride (1.6 g, 5.3 mmol) and 1,1-bis(methylthio)-2-nitroethylene (875 mg, 5.3 mmol) in 12 ml acetic acid was heated at 120° C. overnight. The reaction mixture was cooled to room temperature, 30 ml of water was added and the resulting mixture was extracted with 2×60 ml ethyl acetate. The ethyl acetate extracts were washed with 2×50 ml water, 2×50 ml saturated sodium bicarbonate solution and 50 ml brine, and then dried (anhydrous sodium sulfate), filtered and concentrated in vacuo. The residue was chromatographed on silica gel (440 g, 230-400 mesh), eluting with 85:15 hexane/ethyl acetate to yield the title compound as a yellow solid (1.65 g, 72% yield).
