실험 절차

The product from Example 277B (100 mg, 0.287 mmol) and DMAP (59 mg, 0.480 mmol) in CH2Cl2 (1 mL) was treated with acetic anhydride (38 μL). After stirring for 30 minutes, the mixture was treated with CH2Cl2 (5 mL) and the phases separated. The organic layer was washed with water (10 mL×3), dried (Na2SO4), filtered, and the filtrate was concentrated to provide the title compound. MS (ESI+) m/z 391 (M+H)+; MS (ESI−) m/z 389 (M−H)−; 1H NMR (DMSO, 300 MHz) δ 1.25 (s, 9H), 4.27 (dq, J1 14.9, J2 6.1, 2H), 6.56 (s, 1H), 7.09 (d, J 8.5, 2H), 7.28 (d, J 8.5, 2H), 7.72 (t, J 7.1, 1H), 7.90 (d, J 6.1, 1H), 8.07 (d, J 6.1, 1H), 8.17 (d, J 8.1, 1H), 8.53 (d, J 6.1, 1H), 8.86 (t, J 6.1, 1H), 9.35 (s, 1H); Anal. Calcd for C24H26N2O3+0.8H2O: C, 71.19; H, 6.87; N, 6.92. Found: C, 70.87; H, 6.47; N, 6.92.
