실험 절차

Methanesulfonyl chloride (0.42 mL, 5.39 mmol) was added dropwise at 0° C. to 3-(3-hydroxypropyl)indolin-2-one (1.03 g, 5.39 mmol) and triethylamine (1.13 mL, 8.09 mmol) in dichloromethane (20 mL). The mixture was allowed to warm to room temperature and stirred for 2 hours. The reaction was washed with 2M aqueous hydrochloric acid and brine, dried (MgSO4), and evaporated. The residue was purified by Biotage flash column chromatography (30% ethyl acetate/hexanes) to give product as an oil (1.45 g, quant.); 1H NMR (DMSO-d6); δ1.66-1.70 (m, 2H); 1.85-1.94 (m, 2H); 3.15 (s, 3H); 3.48 (t, J=6.4 Hz, 1H); 4.19 (t, J=6.4 Hz, 2H); 6.82 (d, J=8 Hz, 1H); 6.96 (m, 1H); 7.18 (m, 1H); 7.25 (d, J=7.6 Hz, 1H); 10.4 (s, 1H); MS for C12H15NO4S m/z 270 (M+H)+.
