Reaction Steps
The 1-acetyl-4-(4-piperidinobenzoyl)piperidine (0.63 g) prepared in Example 1 was dissolved in 10 ml of concentrated hydrochloric acid and the solution was stirred at 100° C. for 3 hours. The solvent was then distilled off under reduced pressure and the residue was recrystallized from ethanol to give 0.5 g of colorless crystals melting at 256°-264° C.
