実験手順

To title compound of Step E (0.062 g, 0.146 mmol) in EtOAc (2 mL) was added 4M HCl in dioxane (2 mL). After 18 h, the reaction was neutralized with saturated NaHCO3 (aq.) and extracted with CH2Cl2 (2×). The combined organics were dried and concentrated. Silica gel chromatography (10-80% 2M NH3/MeOH in CH2Cl2) gave 0.029 g (61%) of the title compound. MS (ESI): mass calcd. for C17H16F3NO2, 323.11; m/z found, 324.2 [M+H]+. 1H NMR (CDCl3): 7.73 (d, J=7.8 Hz, 1H), 7.54 (t, J=7.3 Hz, 1H), 7.45 (t, J=7.6 Hz, 1H), 7.32 (d, J=7.6 Hz, 1H), 6.90 (td, J=8.2, 5.1 Hz, 2H), 6.59 (s, 1H), 5.02-4.97 (m, 1H), 3.92 (s, 3H), 3.96-3.85 (m, 7H).
