The reaction of β,γ-unsaturated γ-alkoxy-α-keto esters with N-unsubstituted 5-aminopyrazoles was investigated. The reaction proceeds with high regioselectivity and is considered as an effective method for the preparation of new pyrazolo[1,5-a]pyrimidines bearing an ester function in the 7-position. The obtained drug-like compounds have a great potential for medicinal chemistry as they closely resemble the structure of several marketed pharmaceuticals.
