Reaction Steps

To a solution of ester 17 (1.27 g, 4 mmol) in 40 mL of THF was added LiAlH4 (0.24 mg, 6.4 mmol). The reaction mixture was stirred for 6 hours at room temperature. EtOAC (5 mL) and water (10 mL) were added successively. The solvent was removed in vacuo and the resulting solid was filtered. The crude product was purified by column chromatography (EtOAc/Hexanes=7:3) to give the titled compound (0.97 g, 85%) as a white solid mp 119.5-123.4° C. 1H NMR (300 MHz, DMSO-d6): δ 7.91 (d, J=9 Hz, 2H), 7.46 (d, J=9 Hz, 2H), 7.43-7.37 (m, 3H), 7.31-7.25 (m, 2H), 6.56 (s, 1H), 4.52 (t, J=5 Hz, 1H), 3.54-3.46 (m, 2H), 3.24 (s, 3H), 2.79-2.60 (m, 2H), 1.88-1.77 (m, 2H).
