반응 단계
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.
