Procedure

To a solution containing 2-(4-fluorophenyl)-1-{4-[(2-piperidyl)ethoxy]benzyl}-1,2,3,4-tetrahydroisoquinolin-6-ol (0.100 g, 0.2 mmol) in pyridine (0.4 ml) was added methyl sulfonyl chloride (25 μl, 0.32 mmol). After stirring for five hours, solvent was removed and the reaction was basified with aqueous sodium bicarbonate solution. The reaction was extracted with dichloromethane and concentrated. The product was purified by semipreparative HLPC (C-18 column, 10-100% acetonitrile/water with 0.1% trifluoroacetic acid). The acetonitrile was removed from the HPLC fractions containing the desired product. Ethyl acetate was added and the solution neutralized using saturated sodium bicarbonate. The organic layer was washed with brine, dried over MgSO4, filtered and concentrated to provide the title compound (0.0135 g, 13% yield): 1H NMR (CDCl3) 6.7-7.1 (m, 11H), 4.78 (t,1H), 4.1 (t, 3H), 3.45-3.62 (m, 2H), 2.62-3.18 (m, 8H), 2.58 (m, 4H), 1.63 (m, 4H), 143 (m, 2H); ES-MS (m/z) 539 [M+H]+.
