Reaction Steps

In a mixed solution of 80 ml of ethanol and 30 ml of toluene was dissolved 7.10 g of the mixture of N-acetyl-4[(1-benzyl-4-piperidinyliden)acetyl]aniline and N-acetyl-4[(1-benzyl-1,2,5,6-tetrahydropyridin-4-yl)acetyl]aniline obtained in Reference example 14, and then 0.10 g of platinum oxide was added thereto. The mixture was stirred under a hydrogen stream for 5.5 hours. After the reaction, the catalyst was removed by filtration and condensed under reduced pressure. The residue obtained was applied to silica gel column chromatography to obtain 5.54 g of the title compound.
