実験手順

1.41 g of 4-(diphenylmethoxy)-1-piperidinepropanamine and 1.23 g of N-(6-chloro[1,2,4]triazolo[1,5-b]pyridazine-2-carbonyl)glycine ethyl ester were dissolved in 17 ml of N,N-dimethylformamide; 1.50 ml of N-ethyldiisopropylamine was added, followed by stirring at room temperature for 28 hours, then at 60° C. for 19 hours. After cooling, aqueous sodium bicarbonate was added, followed by extraction with ethyl acetate-tetrahydrofuran (1:1); the extract was dried with magnesium sulfate. The dry product was concentrated under reduced pressure; the residue was subjected to silica gel column chromatography and eluted with ethyl acetate:methanol:triethylamine (50:5:1). The desired fraction was collected, concentrated, recrystallized by the addition of tetrahydrofuran, collected by filtration, washed with ethyl ether and dried to yield 987 mg of the title compound.
