Reaction Steps
To a −15° C. solution of the product of Example 38B (1.34 g, 6.27 mmol) in tetrahydrofuran (25 mL) was added lithium aluminum hydride (0.238 g, 6.27 mmol). The reaction mixture was kept between −5° C. and −15° C. for 1 hour and then quenched by the addition of solid sodium sulfate decahydrate. The quenched reaction mixture was filtered through a pad of celite with ethyl acetate and the filtrate concentrated. The residue was chromatographed on silica gel with 35% ethyl acetate-hexane to give the title compound (0.90 g, 84%). 1H NMR (300 MHz, DMSO-d6) δ ppm 8.49 (dd, J=1.5, 4.6, 1H), 7.85 (dd, J=1.6, 8.1, 1H), 7.26 (dd, J=4.6, 8.1, 1H), 4.70-4.55 (m, 1H), 3.82-3.62 (m, 1H), 3.59-3.39 (m, 2H), 1.16 (d, J=6.5, 3H). MS (DCI) m/z 172 (M+H)+.
