3-Amino-3-phenyl-2-phenylazoacrylonitrile 6 is obtained in good yield via reaction of 5 with phenyl magnesium bromide. The compound 6 is readily converted into 4a. The so formed alkanenitrile reacted with phenylmagnesiumbromide to yield 8. Compound 8 could be also obtained from reaction of 9 with phenylmagnesiumbromide. The arylhydrazononitriles 8 and 4a reacted with chloroacetonitrile to yield the 4-aminopyrazoles
