Reaction Conditions

Reaction Steps

To a solution of 2-(4-fluorophenyl)-5-methoxy-1-{4-[(2-piperidyl)ethoxy]benzyl}isoindoline (0.14 g, 0.3 mmol) in CH2Cl2 (8 mL) under nitrogen at −10° C. was added a 1.0 M solution of boron tribromide in CH2Cl2 (0.6 mL, 0.6 mmol) dropwise. After stirring at −10° C. for 1 hour, the reaction was quenched with ice and saturated sodium bicarbonate, then extracted with methylene choride. The organic layer was dried over MgSO4, filtered, and concentrated. The residue was then purified by HPLC (C-18 column, 10-100% acetonitrile/water with 0.1% trifluoroacetic acid) to provide the title compound (0.084 g, 84% yield): 1H NMR (DMSO-d6) 7.04 (t, 2H), 6.88 (d, 1H), 6.69 (dd, 1H), 6.61-6.65 (m, 5H), 6.56 (d, 1H), 5.21 (m, 1H), 4.67 (s, 1H), 4.51 (s, 1H), 4.29 (d, 1H), 4.10 (dd, 1H), 3.00-3.14 (m, 2H); ES-MS (m/z) 336 [M+H]+.
