Hydrochloric Acid → HCID 13195345, compound

Participants

Reaction Steps

2.62 Grams of 6-morpholinocarbonyl-3,4-dihydrocarbostyril and 17.9 g of 3,4-dimethoxybenzylamine were placed in a sealed tube and heated at 170°-200° C. for 5 hours. Then 3,4-dimethoxybenzylamine was removed by distillation under a reduced pressure and the residue thus obtained was treated by means of a silica gel column chromatography, and the objective product was changed to a hydrochloride by adding concentrated hydrochloric acid. Recrystallized from methanol-water to obtain 0.35 g of 6-[4-(3,4-dimethoxybenzyl)-1-piperazinylcarbonyl]-3,4-dihydrocarbostyril monohydrochloride. Colorless granular crystals. Melting point: 240°-242° C. (decomposed)
