実験手順
Methanesulfonic anhydride (18 mg, 0.11 mmol) was added to a solution of alcohol (7s) (36 mg, 0.076 mmol) and diisopropylethylamine (29 mg, 0.23 mmol) at room temperature. The solution was stirred for 1 hour. Isopropylamine (0.13 mL, 1.50 mmol) was added and the reaction was stirred at room temperature for 60 hours. The volatiles were removed in vacuo. The crude product was purified on silica gel with 5% MeOH/CH2Cl2 containing 1% Et3N and then on C18 silica with CH3CN/H2O to afford the desired compound (8s-2) (8 mg, 20% yield). 1H NMR (400 MHz, MeOD) δ 7.88 (s, 1H), 7.51 (d, J=8.6 Hz, 1H), 7.31-7.24 (m, 3H), 7.17-7.16 (m, 2H), 6.93-6.89 (m, 1H), 6.05 (s, 1H), 4.52 (t, J=10.2 Hz, 2H), 4.41 (s, 2H), 3.57 (s, 3H), 3.35-3.30 (m, 1H), 3.03 (t, J=11.7 Hz, 2H), 2.29-2.22 (m, 2H), 1.29 (d, J=6.3 Hz, 6H), 1.26 (s, 9H); MS (ESI+) m/z 517 (M+H)+; HPLC (5 to 95%) 2.61 min.
