Participants

Reaction Steps

2.7 Grams of 7-(5-bromopentoxy)-3,4-dihydrocarbostyril, 2.0 g of 4-benzylpiperidine and 1.5 g of triethylamine were mixed with 30 ml of dimethylformamide and the mixture was heated at 60°-70° C. for 6 hours. The reaction mixture was then concentrated under a reduced pressure to dryness, and to the residue thus obtained was added a 5%-sodium hydrogencarbonate aqueous solution and stirred. The insoluble matters thus formed were collected by filtration, washed with water and dried. Recrystallization from ligroin to obtain 3.6 g (yield: 88%) of 7-[5-(4-benzyl-1-piperidyl)pentoxy]-3,4-dihydrocarbostyril as in the form of colorless plate-like crystals. Melting point: 100°-102° C.
