Direct synthetic methods of 6,7‐diphenylpyrazolo[1,5‐ a ]pyrimidine derivatives have been developed. Cyclocondensation of isoflavones with 3‐aminopyrazole in the presence of sodium methoxide as alkali promoter gave 6,7‐diphenylpyrazolo[1,5‐ a ]pyrimidines in moderate to good yields. J. Heterocyclic Chem., (2011).
