Reaction Steps

A solution of ethyl 3-cyclopropyl-3-(1,1-dimethylethylsulfinamido)butanoate (1.16 g, 4.21 mmol) in ammonia 7N in methanol (20 ml, 140 mmol) in a microwave sealed tube was stirred at 45° C. overnight. The volatiles were removed in vacuo and the residue was directly purified by flash chromatography on silica eluting with a gradient of dichloromethane/methanol to yield the title compound (155 mg, 15%); MS (ESI, m/z): 247.2 (M+H+).
