with ammonia;potassium carbonate in methanol at 140 - 150;

Steps:

Step B: piperidine-4-carboxamide

To a mixture of methyl piperidine-4-carboxylate (590g, 3.10mol) in NH3/MeOH (4.5L, V/V 40) was added K2CO3 (5.0g, 36mmol) . The resulting reaction mixture was heated to 140-150 overnight. The next day the solvent was removed on the rotary evaporator, and the crude product recrystallized by CH3OH/EtOAc to afford the title compound.
