Synthesis of 4-Amino-3,5-dicyano-arylpyrazoles, Part 2: Isolation and Characterization of By-Products
摘要:
Reaction of (dicyanomethylidene-hydrazino) benzoic acids with chloroacetonitrile, under basic conditions, gave cyanomethyl-3-(7-amino-3,5-dicyano-1H-pyrazolo[4,3-d]pyrimidin-1-yl-benzoates and para-substituted cyanomethyl benzoates, in addition to the expected cyanomethyl 3-(4-amino-3,5-dicyano-1H-pyrazol-1-yl)-benzoates.
