A new facile and straightforward method for synthesis of 2-methyl-6,7-diphenyl- pyrazolo[1,5-a]pyrimidines has been described. The cyclocondensation of isoflavones with 3-amino-5-methylpyrazole in the presence of sodium methoxide gave fused 2-methyl-6,7-diphenylpyrazolo[1,5-a]pyrimidines in moderate to good yields. A series of 20 new compounds were obtained and characterized by FT-IR, NMR, and elemental analysis.
