Synthesis and biological activities of some new formazans, part-I

1-(Phenyl-3-(2-methoxy-4-N,N'-bis-2'-cyanoethylamino phenyl) p-tolyl formazans have been synthesised by first reacting 4-N,N'-bis-2-cyanoethylamino-2-methoxy benzaldehyde with p-tolyl hydrazide which gave the acid hydrazone. The acid hydrazone on treatment with diazotised aromatic amines in pyridine medium furnished fifteen formazans in 40 to 54% yield. The acid hydrazone and the formazans were found to be devoid of anticancer and anti-HIV activities.
