Abstract Two species of N-arylpyrazoles containing active amino group were synthesized.And formylations of N-arylpyazoles containing amino in different position of pyrazole rings using Vilsmeier-Hacck reaction gave a series of useful pyrazole intermediates.The important features of this protocol were cheap materials, easy process, mild reaction conditions and good yield of products.
