실험 절차

Compound 27 (1.00 g, 5.8 mmol) in THF (20 mL) was added slowly to a solution of LAH (1.76 g, 46.4 mmol) in THF (45 mL) at 0° C. The solution was allowed to warm to room temperature and the reaction was stirred overnight. The reaction was cooled to 0° C. and quenched with H2O. The solids were filtered from the solution through celite and washed with hot THF. The filtrate was concentrated and the residue was dissolved in EtOAc (80 mL) and washed with 1 M HCl (3×30 mL). The aqueous layer was basified with 6 M NaOH to a pH of 12 and the precipitate was extracted with EtOAc (3×30 mL). The resulting organic solution was washed with brine (40 mL), dried with Na2SO4 and filtered. Concentration afforded a slightly yellow solid (510 mg, 56% yield). m.p. 55-56° C. 1H NMR (CDCl3) δ 7.80 (3H, ArH), 7.72 (s, 1H, ArH), 7.43 (m, 3H, ArH), 4.00 (s, 2H, ArCH2). 13C NMR (CDCl3) δ 140.6, 133.5, 132.5, 128.2, 127.7, 126.1, 125.8, 125.5, 125.1, 46.6. IR (KBr) vmax cm−1: 3362, 3291, 3050, 2915, 1950, 1596, 1507, 1358, 1273. GC: r.t.=8.97 min. EI-MS m/z (%) 157 (83, M+), 156 (100), 141 (15), 129 (49), 128 (40), 127 (24), 115 (10).
