Procedure

To a solution of 2-(4-fluorophenyl)-1-{4-[(2-piperidyl)ethoxy]benzyl}-1,2,3,4-tetrahydroisoquinolin-6-ol (0.100 g, 0.2 mmol) in THF (I ml) and DMF (5 drops) on ice was added sodium hydride (0.024 g, 0.6 mmol). To the flask was added bromoacetamide (0.083 g, 0.6 mmol). While warming to room temperature the reaction was allowed to stir for 6 hours. The reaction was quenched with an aqueous solution of sodium bicarbonate and extracted with dichloromethane. The organic layer was dried over MgSO4, filtered and concentrated. The product was purified by HPLC as described above to yield the title compound (0.005 g, 4.8% yield): ES-MS (m/z) 518 [M+H]+.
