Procedure

A solution of 1-{4-(phenylmethoxy)benzyl}-6-methoxy-2-phenyl-1,2,3,4-tetrahydroisoquinoline (0.60 g, 1.38 mmol), palladium (5% wt. on activated carbon, 0.06 g), and glacial acetic acid (3 drops) in ethanol (30 mL) was stirred under hydrogen for 15 hours. The reaction was filtered and concentrated to provide the title compound (0.30 g, 63% yield): ES-MS (m/z) 346 [M+H]+.
