To a solution of 355 mg of t-butyl 4-(2-ethoxy-2-oxoethylidene)tetrahydropyridine-1(2H)-carboxylate in 10 ml of methanol, 50 mg of 10% palladium-on-carbon catalyst was added and stirred for 13 hours in 3 atmospheres' hydrogen pressure. Filtering the catalyst off, the solvent was distilled off under reduced pressure to provide 334 mg of the title compound.
