Procedure

1.8 Grams of 6-[1-oxo-3-(4-phenyl-1-piperazinyl)-propyl]-3,4-dihydrocarbostyril and 0.24 g of of sodium hydride (50% in mineral oil) were mixed in 50 ml of dimethylformamide and stirred at a room temperature for 3 hours. Then 0.9 g of p-toluenesulfonic acid was added and stirred at a room temperature for 3 hours. The reaction mixture was poured into 150 ml of a saturated sodium chloride solution and was extracted with chloroform. The chloroform layer was washed with water, dried and chloroform was removed by distillation under a reduce pressure. The residue thus obtained was injected into preparative thin-layer chromatography to purify and separate the desired compound. The compound obtained was dissolved in acetone and converted into the oxalate by a method similar to that described in Example 27 and recrystallized from ethanol-water to obtain 1.5 g of 1-methyl-6-[1-oxo-3-(4-phenyl-1-piperazinyl)propyl]-3,4-dihydrocarbostyril.monooxalate in colorless flake-like crystals.
