6-Chloro-3-(trifluoromethyl)-(1,2,4)triazolo(4,3-b)pyridazine → HCID 67339692, compound

Participants

Reaction Steps

A mixture of 1-piperidin-4-yl-3,4-dihydroquinolin-2-one hydrochloride and 6-chloro-3-(trifluoromethyl)-[1,2,4]triazolo[4,3-b]pyridazine was allowed to react by General Synthetic Method 4. The crude product was purified by hplc using a Phenomenex Luna C18 100A column (10μ silica, 21 mm diameter, 150 mm length) eluted with decreasingly polar mixtures of water (containing 0.1% aqueous ammonia) and acetonitrile as eluents to give 1-[1-[3-(trifluoromethyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl]piperidin-4-yl]-3,4-dihydroquinolin-2-one.
