Reaction Steps

A solution of 2-[4-(2-Nitro-benzenesulfonylamino)-isoxazolidine-2-carbonyl]-benzoic acid methyl ester (200 mg, 0.46 mmol) and PhSH (0.035 ml, 1.1 equiv) in acetonitrile (2.3 ml) under argon at rt was treated with K2CO3 (95 mg, 1.5 equiv). The reaction mixture turned bright yellow. The reaction was left to stir overnight. As TLC indicated complete consumption of starting material, volatiles were removed in vacuo. Flash column chromatography eluting with dichloromethane:methanol (9/1) afforded 85 mg of the expected amine (0.34 mmol, 74%). LCMS (Method E) 0.55 and 1.41 min, M+H 251. 1H-NMR (CDCl3, 400 MHz): 7.95 (d, 1H), 7.63-7.52 (m, 1H), 7.51-7.36 (m, 2H), 4.17-3.92 (m, 3H), 3.87 (s, 3H), 3.80-3.55 (m, 2H), 2.04-1.75 (m, 2H).
