Microwave-assisted synthesis of substituted 2-amino-1H-imidazoles from imidazo[1,2-a]pyrimidines
摘要:
An efficient method for the synthesis of mono- and disubstituted 2-amino-1H-imidazoles via microwave-assisted hydrazinolysis of substituted imidazo[1,2-a]pyrimidines is reported. This protocol avoids strong acidic conditions and is superior to the classical cyclocondensation of alpha-haloketones with N-acetylguanidine. (C) 2009 Elsevier Ltd. All rights reserved.
