## Abstract 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.
