Reaction Steps

Palladium hydroxide on carbon (˜10% Pd, 84 mg, 0.06 mmol) was added to a mixture of 1-(1-(benzyloxycarbonyl)piperidin-4-yl) 4-tert-butyl 2-((pyridin-3-yloxy)methyl)piperazine-1,4-dicarboxylate (0.665 g, 1.20 mmol) and ammonium formate (0.151 g, 2.40 mmol) in EtOH (10 mL). The reaction mixture was heated to 70° C. for 2 h. Upon cooling to rt, the reaction mixture was filtered though Celite®, and the filtrate was concentrated under reduced pressure. This gave 0.5278 g of crude product. LC-MS: RT=4.50 min, [M+H]+=421.2.
