The reactions of 2-substituted 4-chlorobenzofuro [3, 2-d] pyrimidine with hydrazine hydrate gave the corresponding hydrazides. The treatment of hydrazides with ethyl acetoacetate, ethyl cyanoacetate and acetyl acetone afforded 4-pyrazolyl benzofuro [3, 2-d] pyrimidines. The condensation of 4-hydrazide with different aldehydes gave arylidene hydrazino derivatives.
