Sodium hydride → HCID 69890625, compound

Participants

Reaction Steps

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 (1 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 sit 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 semipreparative HPLC (C-18 column, 10-100% acetonitrile/water with 0.1% trifluoroacetic acid) to yield the title compound (0.008 g, 7.0% yield):1H NMR (CDCl3) 6.6-7.3 (m, 11H), 6.0 (broad s, 2H), 5.55 (broad s, 1H), 4.7 (t, 1H), 4.5 (s, 2H), 4.1 (m, 4H), 3.5 (m, 2H), 3.05 (m, 1H), 2.9 (m, 4H), 2.65 (m, 1H), 2.55 (m, 4H), 1.65 (m, 4H), 1.5 (m, 2H); ES-MS (m/z) 575 [M+H]+.
