Reaction Steps

3-(3-(4-(4-Fluorophenyl)piperazin-1-yl)propyl)-4,5,6,7-tetrahydro-2H-pyrazolo[4,3-c]pyridine (0.3 g) obtained in Example 141 was dissolved in a mixed solution of chloroform (5 ml) and saturated aqueous sodium hydrogencarbonate solution (5 ml), and acetyl chloride (0.3 ml) was added dropwise under ice-cooling. After the dropwise addition, the chloroform layer was partitioned and dried over magnesium sulfate. The solvent was evaporated under reduced pressure and the obtained residue was subjected to silica gel column chromatography to give 5-acetyl-3-(3-(4-(4-fluorophenyl)piperazin-1-yl)propyl)-4,5,6,7-tetrahydro-2H-pyrazolo[4,3-c]pyridine.
