2.2. Synthesis of 2-arylhydrazono-3-ketiminobutyronitriles (1a–k) and 5-amino-4-arylazo-3-methyl-1-phenylpyrazoles (2a–k)
2-Arylhydrazone-3-ketiminobutyronitriles (1a–k) and 5-amino-4-arylazo-3-methyl-1-phenylpyrazoles (2a–k) were prepared according to the literature procedures [16], [33] and [34]. The general route for the synthesis of 2-arylhydrazono-3-ketiminobutyronitriles and 5-amino-4-arylazo-3-methyl-1-phenylpyrazoles Torin 1 outlined in Scheme 1.
