実験手順

A solution of 3-methanesulfonylamino-2-phenyl-4-carboxylic acid (1c) (250 mg, 0.73 mmol), HOBt hydrate (148 mg, 1.1 mmol), 4-methylmorpholine (160 μL, 1.46 mmol) in methylene chloride (15 mL) was added EDCI (210 mg, 1.1 mmol) at RT under N2. A mixture of (1R,2S)-1-amino-1-phenylpropan-2-ol hydrochloride and 4-methylmorpholine (193 μL, 1.75 mmol), in methylene chloride (5 mL) was added and the reaction mixture was stirred at RT for 16 h. Solution is partitioned against water and twice extracted with methylene chloride. The combined organic extracts are washed with brine, dried over magnesium sulfate and then concentrated in vacuo with added silica. The compound is subsequently eluted off the silica and chromatographed, eluting with 15-30% ethyl acetate/dichloromethane to give the title compound (167 mg, 48%). 1H NMR (500.333 MHz, CDCl3) δ 1.10 (d, J=6.6 Hz, 3H), 2.23 (s, 3H), 2.69 (d′, J=6.7 Hz, 1H), 4.44-4.47 (m, 1H), 5.35 (dd, J=8.4, 3.3 Hz, 1H), 7.35 (d, J=7.2 Hz, 1H), 7.39 (dd, J=6.9, 6.9 Hz, 2H), 7.44 (d, J=7.5 Hz, 2H), 7.47-7.55 (m, 4H), 7.71-7.78 (m, 4H), 8.16 (d, J=8.4 Hz, 1H) MS APCI, m/z=476.1 (M+1). LCMS: 1.86 min.
