Reaction Steps

To a solution of 1-(4-bromobenzyl)-6-methoxy-2-phenyl-1,2,3,4-tetrahydroisoquinoline (0.10 g, 0.25 mmol) in CH2Cl2 (15 mL) at 0° C. under nitrogen was added boron tribromide (1.47 mL, 1.47 mmol). The reaction was allowed to reach RT. After 8 hours, the reaction was poured into water (10 mL) and neutralized with saturated sodium bicarbonate. Additional CH2Cl2 (25 mL) was added, the organic layer was separated, dried over MgSO4, filtered and concentrated. The residue was then chromatographed (SiO2, 2:1, hexanes/ethyl acetate) to provide the title compound (0.010 g, 10% yield): 1H NMR (CDCl3) 7.33 (d, 2H), 7.24 (dd, 2H), 6.97 (d, 1H), 6.88 (d, 2H), 6.80 (d, 2H), 6.75 (dd, 2H), 6.66 (m, 1H), 6.27 (s, 1H), 4.78 (t, 1H), 3.53 (m 2H), 3.13 (dd, 1H), 2.96 (m, 2H), 2.62 (m, 1H); ES−MS (m/z) 392 [M−H]−.
