Versuchsvorschrift

0.311 g of 4-(diphenylmethyl)-1-piperazinepropanol was dissolved in 5 ml of N,N-dimethylformamide; 0.048 g of 60% oily sodium hydride was added; the reaction mixture was stirred in an oil bath (60° C.) for 30 minutes. After cooling, 0.232 g of 6-chloro[1,2,4]triazolo[4,3-b]pyridazine was added; the reaction mixture was stirred in an oil bath. (bath temperature 60° C.) for 40 minutes. After cooling, 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 (90:10:1). The desired fraction was collected and concentrated; the crystal obtained was filtered, washed with ethyl ether, and dried, to yield 0.339 g of the title compound.
