Synthesis of Mono- and Disubstituted 1H-Imidazo [1,2-B] Pyrazoles

Synthesis of Mono- and Disubstituted 1H-Imidazo [1,2-B] Pyrazoles

The improved synthesis of 1H-imidazo[l,2-b]pyrazole 1 and of mono- and disubstituted derivatives is described and representative experimental procedures are given. Namely, 2-, 3-, 7- and 6-monosubstituted (2-15k), 2,3- and 6,7- disubstituted (16,17) compounds are prepared and characterized.
