実験手順

By substituting 4-hydrazino-1-furfurylpyrazolo[3,4-b]pyridine-5-carboxylic acid, ethyl ester for the 1-ethyl-4-hydrazino-1H-pyrazolo[3,4-b]pyridine-5-carboxylic acid,ethyl ester in Example 1 (a), 8-furfuryl-4H-pyrazolo[4',3'-5,6]pyrido[3,4-e][1,2,4]triazolo[1,5-a]pyrimidin-5(8H)-one is obtained. This compound is now processed as in Example 1 (b) and then as in Example 4, substituting phenol for the ethanol to obtain 8-furfuryl- 5-phenyloxy-8H-pyrazolo[4',3':5,6]pyrido[3,4-e][1,2,4]triazolo[1,5-a]pyrimidine.
