Reaction Steps

Prepared from the intermediate obtained in Step A by the procedure described in Example 218, Step A. Silica gel chromatography (95:5 hexane/EtOAc) provided a colorless crystalline solid (0.323 g, 88%). 1H NMR (CDCl3, 300 MHz): δ 9.74 (s, 1H), 7.41 (s, 1H), 7.22-7.28 (m, 3H), 7.06-7.13 (m, 3H), 6.72-6.80 (m, 2H), 5.00 (s, 2H), 3.91 (sept, 6.8 Hz, 1H), 3.23 (sept, 6.7 Hz, 1H), 2.37-2.46 (m, 1H), 2.17-2.27 (m, 1H), 1.20-1.36 (m, 14H), 0.73 (t, 7.4 Hz, 3H). FAB-MS: calculated for C29H33FO2 432; found 433 (M+H).
