Reaction Conditions

Reaction Steps

18.61 g iron powder in 198 ml ethanol and 1.93 ml conc. hydrochloric acid were stirred for 30 minutes at room temperature. 7.8 g (27.34 mmol) (RS)—S-(3-nitrophenyl)-N-(isopropylcarbamoyl)-S-methylsulfoximide in 20 ml methanol were added. The mixture was stirred at 60° C. for 2 hours and filtered over a bed of silica gel. The residue was washed with hot ethanol. The combined filtrates were evaporated. The crude residue was purified by column chromatography (silica gel, dichloromethane:dichloromethane/ethanol 1:1) to give 4.53 g (65% yield) of the title compound.
