Procedure
A mixture of ethyl N-tert-butoxycarbonyl-4-(2-chloro-6-methylpyridin-4-ylmethyl)piperidine-4-carboxylate (0.32 g, 0.81 mmol) and 5% palladium on charcoal (60 mg) in methanol (10 mL) was stirred under a balloon of hydrogen gas at room temp. for 3 h. The resultant mixture was filtered through a plug of Celite. The filtrate was concentrated under vacuum. The residue was subjected to column chromatography on silica gel eluting with 3-5% methanol in chloroform gradient. Collection and concentration of appropriate fractions provided the title compound.
