Reaction Steps

A solution of 1-(4-hydroxybenzyl)-6-methoxy-2-phenyl-1,2,3,4-tetrahydroisoquinoline (0.30 g, 0.87 mmol), 2-chloroethylpiperidine hydrochloride (0.32 g, 1.74 mmol) and potassium carbonate (0.24 g, 1.74 mmol) in dimethyl formamide (15 mL) was heated to 80° C. After 6 hours, the mixture was cooled to RT, poured into water (30 mL), and neutralized using a saturated solution of ammonium chloride. The product was extracted with ethyl acetate (2×75 mL), dried over MgSO4, filtered and concentrated. The residue was then chromatographed (SiO2, 10:1 ethyl acetate/ethanol) to provide the title compound (0.20 g, 47% yield): ES-MS (m/z) 457 [M+H]+.
