Potassium Carbonate → HCID 23000343, compound

Participants

Reaction Steps

0.552 g of 6-[3-[4-(diphenylmethoxy)piperidino]propoxy][1,2,4]triazolo[4,3-b]pyridazin-3(2H)-one was suspended in 3 ml of N,N-dimethylformamide; 0.200 g of potassium carbonate and 0.209 ml of chloromethyl pivalate were added, followed by stirring at room temperature for 20 hours. After ice water was added, the reaction mixture was extracted with ethyl acetate; the extract was washed with saline and dried over magnesium sulfate. After concentration under reduced pressure, the residue was subjected to silica gel column chromatography and eluted with ethyl acetate-methanol-triethylamine (185:15:2). The desired fraction was collected and concentrated; the crystal obtained was filtered, washed with siethyl ether-hexane (1:1), and dried, to yield 0.515 g of the title compound.
