摘要

A new synthesis of 1-alkylpyrazolo [5, 4-d] pyrimidines is described. The reaction of 4, 6- dichloropyrimidine-5-carbaldehyde with various substituted hydrazines provides such compounds in a single step from commercially available starting materials. This method has advantages over methods currently described in the literature for the construction of such ring systems.
