1-Propanol → HCID 86754296, compound

Participants

Reaction Steps

A mixture comprising 2.4 g of 3-[4-(2-quinolylmethyl)-piperazin-1-yl]-carbonylmethoxy-4-methoxybenzylamine, 1 g of 4,5-dichloro-6-ethoxy-3(2H)-pyridazinone, 580 mg of triethylamine, 10 ml of propanol and 10 ml of water, was refluxed under heating with stirring overnight. The solvent was distilled off under reduced pressure, and the residue was extracted with chloroform. The organic layer was washed with an aqueous potassium carbonate solution and then dried over anhydrous sodium sulfate. Then, the solvent was distilled off. The obtained residue was purified by silica gel column chromatography (ethyl acetate:methanol=6:1→chloroform:methanol=12:1) and then crystallized from diethyl ether to obtain 1.5 g of the above-identified compound as white crystals.
