Synthesis of new 3(5)-(2-hydroxyphenyl)pyrazoles as potential analgesic agents and platelet aggregation inhibitors

Reactions of 2-methyl-3-nitrochromen-4-one 1 with hydrazine, methylhydrazine and phenylhydrazine readily gave 3(5)-(2-hydroxyphenyl)-5(3)-methyl-4-nitropyrazoles 4a-d which were converted to 3(5)-(2-methoxyphenyl-5(3)-methyl-4-nitropyrazoles 5b-d by treat
