実験手順

Methanesulfonic anhydride (12 mg, 0.070 mmol) was added to a solution of alcohol (7s) (24 mg, 0.050 mmol) and diisopropylethylamine (20 mg, 0.15 mmol) at room temperature. The solution was stirred for 1 hour. Dimethylamine (2.0 M in THF, 0.25 mL, 0.50 mmol) was added and the reaction was stirred overnight. Additional dimethylamine was added (2.0 M in THF, 0.25 mL, 0.50 mmol) and the reaction was stirred an additional 2 days. The mixture was then partitioned between CHCl3 and water. The aqueous phase was extracted once with CHCl3. The organic phases were combined, dried (MgSO4), filtered, and concentrated in vacuo. The crude product was purified on silica gel with 5% MeOH/CH2Cl2 containing 1% Et3N to provide the desired compound (8s-1) (11 mg, 43% yield) as a dark foam. 1H NMR (400 MHz, CDCl3) δ 7.81 (s, 1H), 7.42 (s, 1H), 7.35-7.33 (m, 2H), 7.19-7.11 (m, 4H), 6.80-6.75 (m, 2H), 5.94 (s, 1H), 5.55 (m, 1H), 4.43 (d, J=6.6 Hz, 2H), 4.38 (t, J=10.5 Hz, 2H), 3.57 (s, 3H), 2.24 (t, J=10.5 Hz, 2H), 2.19 (s, 6H), 2.08-2.01 (m, 2H), 1.24 (s, 9H); MS (ESI+) m/z 503 (M+H)+; HPLC (5 to 95%) 2.59 min.
