実験手順

A solution of intermediate 134, 2-(benzyloxy)-4-fluorobenzonitrile, (9.03 g, 39.7 mmol) in ethanol (100 mL) and ethyl acetate (100 mL) was stirred with 10% palladium on carbon (1.67 g,) and concentrated hydrochloric acid (12 mL, 144 mmol) under a hydrogen atmosphere (60 psi) for four days. The catalyst was removed by filtration through Celite, and the filtrate was concentrated. The crude product was triturated with ether and the resulting solid collected by filtration to give the title compound (5.24 g, 74% yield) as a pale orange solid. 1H NMR (500 MHz, DMSO-D6) δ ppm: 10.81 (1 H, s), 8.18 (3 H, s), 7.36 (1 H, t, J=7.3 Hz), 6.79 (1 H, dd, J=10.8, 2.6 Hz), 6.66 (1 H, dt, J=8.5, 2.3 Hz), 3.90 (2 H, d, J=5.2 Hz).
