Synthesis of new 6-halogeno-imidazo[1,2-a]pyridines by SRN1 reactions
Résumé
New 2-chloromethyl-6-halogeno-imidazo[1,2-a]pyridines and 2-chloromethyl-6-halogeno-3-nitroimidazo[1,2-a]pyridines were prepared and reacted under experimental conditions of S RN 1 reactions with different sulfur and carbon centered nucleophiles to give new 6-halogeno-2-substituted-imidazo[1,2-a]pyridines and 6-halogeno-3-nitro-2-substituted-imidazo[1,2-a] pyridines in good yields. Only the chloromethyl group was found to be reactive under these experimental conditions.
