Reaction Steps

To a solution of 1-benzyl 3-methyl (3R,4S)-4-[4-(4-cyano-2-methylphenyl)piperazin-1-yl]carbonylpiperidine-1,3-dicarboxylate (0.5265 g, 0.001043 mol) in methanol (11.00 mL, 0.2716 mol) was added 10% palladium (93.9 mg, 0.0000883 mol) on carbon at room temp. The reaction mixture was stirred under hydrogen balloon at 1 atm pressure overnight. After overnight stirring reaction mixture was filtered and concentrated to give the product in quantitative yield. MS (ESI): (M+H)+=371.
