Two-Step Regioselective Synthesis of 3-(Sulfonylamino)imidazo[1,2-a]pyrimidines from 2-Aminopyrimidines and N-(2,2-Dichloro-2-phenylethylidene)arensulfonamides

Article abstract of DOI:10.1002/ejoc.201402695

The reaction of 2-aminopyrimidines with N-(2,2-dichloro-2-phenylethylidene)arenesulfonamides affords the corresponding products of nucleophilic addition to the azomethine group, N-[2,2-dichloro-2-phenyl-1-(heterylamino)ethyl]sulfonamides, in good yields.
