Reaction Steps

To a mixture of 1.2 g of 6-(1-piperazinyl)-3,4-dihydrocarbostyril, 1.17 g of potassium carbonate and 20 ml of hexamethylphosphoric triamide was added 651 mg of 4-hydroxybenzyl chloride and the mixture was stirred at 90° C. for 2.5 hours. The reaction mixture was poured into a large amount of water and extracted with chloroform. After washing with water, the extract was dried over anhydrous sodium sulfate. Chloroform was distilled off and the residue was purified through silica gel column chromatography to give 0.3 g of 6-[4-(4-hydroxybenzyl)-1-piperazinyl]-3,4-dihydrocarbostyril.
