A mixture of 22.1 g of 4-phenyl-1(2H)-isoquinolone, 20 g of anhydrous potassium carbonate and 100 ml of dimethylformamide was stirred for 2 hours at 100° C. Then, 11 g of 3-chloropropanol was added to the resulting solution and the mixture was stirred at 110° C. for 5 hours. After completion of the reaction, the solvent was distilled off, and the residue was dissolved in dichloromethane. Water was added to the resulting solution and, after thoroughly stirring, the dichloromethane layer was separated and dried over anhydrous sodium sulfate. The solvent was distilled off, and the resulting residue was recrystallized from a mixture of ethyl acetate and petroleum ether to obtain 23 g of 2-(3-hydroxypropyl)-4-phenyl-1(2H)-isoquinolone having a melting point of 84° C. as colorless prisms.
