An efficient synthetic protocol was devised for the synthesis of 3,5-disubstituted 2,6-dicyanoaniline from malononitrile, aldehydes, and β-nitro-olefins by using N,N-dimethyl-4-aminopyridine (DMAP) as a nucleophilic catalyst. The important aspects of the present methodology are: use of non-toxic organo-catalyst, shorter reaction time, compatibility with wide range of substrates, and good yields.
