Reaction Steps

To a solution of 0.218 g (0.68 mmol) of 1-t-butoxy carbonyl-4-(3-phenyl-1-hydroxypropyl)piperidine (Example 239) and 0.3 mL of methyl iodide in 2 mL of DMF was added 0.066 g (1.5 mmol)of NaH (60% dispersion in mineral oil) and the mixture was stirred for 16 h at rt. To the reaction was added 5 mL of water and the mixture was extracted with ethyl acetate. The combined organic fractions were washed with sat'd NaCl solution, dried over MgSO4, filtered and the filtrate was concentrated. The residue was purified by chromatography (silica, hexanes:ethyl acetate, 4:1) to give 1-t-butoxy carbonyl-4-(3-phenyl-1-(RS)-methoxypropyl)piperidine. Removal of the BOC protecting group was achieved as described in Example 233, Step 6 to give the title compound.
