Reaction Steps

The intermediate obtained in Step G (7.7 g, 24.7 mmol) was dissolved in absolute ethanol (200 mL) under argon, treated with 10% palladium on carbon (610 mg, 0.1 eq), then stirred under a hydrogen atmosphere for 2 hr. After purging the system with argon, the catalyst was removed by filtration through a pad of Celite. The solvent was removed and the product dried in vacuo to afford the title compound as a white solid (7.7 g, 25 mmol, 99%). 1H NMR (300 MHz, CDCl3): δ 7.32 (s, 1H), 7.15 (m, 4H), 4.33 (m, 2H), 3.39 (septet, J=7 Hz, 1H), 3.32 (septet, J=7 Hz, 1H), 2.37 (q, J=7.7 Hz, 2H), 1.29 (m, 13H), 0.92 (t, J=7.7 Hz, 3H). FAB-MS calculated for (C21H27FO) 314, found 314 (M+). mp 106-108° C. Rf=0.1 (50% dichloromethane/hexane).
