Procedure

A solution of 1-(1-acetyl-4-methoxycarbonylpiperidin-4-ylmethyl)-4-benzyloxycarbonyl-2-oxo-1,2,3,4-tetrahydropyrazine (2.4 g) and 10% palladium on carbon (500 mg) in methanol (100 ml) was stirred at room temperature for 15 hours, under hydrogen atmosphere, and the catalyst was filtered off. The reaction solution was concentrated to give colorless oil of the title compound (1.40 g).
