Synthesis of 4-benzylpyrazoles from monobenzylmalononitrile

Article abstract of DOI:10.1080/00397919308013289

The hitherto unknown 4-benzylpyrazoles can be prepared in three steps by monobenzylation of malononitrile, reaction with hydrazines to form 3,5-diamino-4-benzylpyrazoles, followed by double deamination.
