Procedure

0.01 mol. of 1-furfuryl-4-phenyl-4H-pyrazolo[4',3':5,6]pyrido[3,4-e][1,2,4]triazolo[1,5-a]pyrimidin-5(8H)-one is heated in 50 ml. of diethyleneglycol dimethylether containing 0.01 mol. of selenium dioxide at reflux temperature with stirring for two hours. The mixture is filtered hot and evaporated to dryness. 4-Phenyl-4H-pyrazolo[4',3':5,6]pyrido[3,4-e][1,2,4]triazolo[1,5-a]-pyrimidin-5(8H)-one remains.
