3-Diethylaminoacrylonitrile (1) reacts with hydrazonyl halides (2a-d) to yield 1,3-disubstituted pyrazole-4-carbonitriles 5a-d. The acetyl 1-p-chlorophenylpyrazole-4-carbonitrile (5a) condensed with hydrazine hydrate to yield the bishydrazone 10 and with dimethylformamide dimethylacetal to yield 1-a
