A new approach to the synthesis of 2-aminoimidazo1,2-apyridine derivatives through microwave-assisted N-alkylation of 2-halopyridines

摘要

A microwave (focused waves) assisted N-alkylation of 2-halopyridines provides a convenient entry to 2-amino-imidazo[1,2-a]pyridine derivatives after reaction of the alkylated substrates with cyanamide under basic conditions.
