Reaction Steps

To a solution of 4-(N-(4-chlorobenzyl)aminocarbonyl)-1-t-butoxycarbonylpiperidine (1.76 g, 5.0 mmol) in dry tetrahydrofuran (20 mL) stirring under argon at room temperature, was added borane-tetrahydrofuran complex (1.0 M in tetrahydrofuran, 20 mL, 20 mmol). The resulting solution was heated to 80° C. for 16 h before cooling to 0° C. Saturated aqueous ammonium chloride (20 mL) was added, and the resulting mixture was stirred for 30 min before extraction with ethyl acetate (25 mL three times). The combined extracts were dried (anhydrous sodium sulfate) and evaporated under vacuum to obtain a gum, which was purified by column chromatography (silica gel, 100% ethyl acetate) to provide 4-(N-(4-chlorobenzyl)aminomethyl)-1-t-butoxycarbonylpiperidine (1.37 g, 81% yield) as a white solid.
