Procedure

2.5 Grams of 4-methyl-6-(3-chloropropoxy)carbostyril, 1.8 g of sodium iodide were mixed with 50 ml of acetone and the mixture was stirred at 50° C. for 1 hour, then 50 ml of dimethylformamide was added and acetone was removed by distillation under a reduced pressure. To the residue thus obtained was added 1.5 g of triethylamine and 1.6 g of 4-benzylpiperidine and the mixture was heated at 70°-80° C. for 7 hours under stirring condition. The reaction mixture was then concentrated under a reduced pressure to dryness and to the residue thus obtained was added 60 ml of a 5%-sodium hydrogencarbonate aqueous solution and stirred to obtain the insoluble matters. The insoluble matters were collected by filtration, washed with water and then recrystallized from methanol to obtain 3.2 g (yield: 82%) of 4-methyl-6-[3-(4-benzyl-1-piperidyl)propoxy]-carbostyril as in the form of yellowish prism-like crystals. Melting point: 177°-178° C.
