4.08 g (16.3 mmol) of the t-butyl (S)-N-acetyl-5-vinyl-1,2,3,4-tetrahydropyridine-2-carboxylate obtained in Synthesis Example 16 was dissolved in 150 mL of ethanol, followed by the addition of 4.0 g of 10% Pd/C. It was treated in a hydrogen atmosphere of 3 kg/cm2 by the use of medium pressure catalytic reaction equipment to conduct hydrogenation. The catalyst was removed by filtration and the filtrate was concentrated to give 140 mg of the title compound. Yield 100%.
