Preparation of 1-Alkyl-2-aryl-1H-imidazo[4,5-b]pyridines from 2-Alkylamino-3-aminopyridines and Aromatic Aldehydes Using Air as an Oxidant
摘要:
Attempted imine formation between 2-methoxyethylamino-3-aminopyridine (an exemplary 2-alkylamino-3-aminopyridine) and an array of aromatic aldehydes in methanol and ambient atmosphere led to the predominant formation of 1-methoxyethyl-2-aryl-1H-imidazo[4,5-b]pyridines. The reaction was found to be of immediate preparative importance in the six cases studied.
