Abstract

Abstract A variety of 3-aryl-4-formylpyrazoles can be easily prepared in good yields from the corresponding methyl ketones, upon treatment with 2, 4, 6-trichloro [1, 3, 5] triazine in N, N- dimethyl formamide at room temperature. This kind of pyrazole can constitute new building blocks for combinatorial chemistry.
