Pyridine → HCID 21493313, compound

Participants

Reaction Steps

A solution of 2-amino-4-nitro-6-ethoxypyridine (29.4 grams) in absolute ether (150 ml), and pyridine (25 grams) are charged into a glass reaction vessel equipped with stirrer, thermometer and addition funnel. The mixture is cooled to a temperature of about 0° C and chloroacetyl chloride (11.3 grams) dissolved in ether (50 ml) is then slowly added thereto with stirring over a period of about 20 minutes. Stirring and cooling are continued for an additional period of about 30 minutes. The resulting precipitate is then recovered from the reaction medium by filtration, is washed first with aqueous sodium carbonate and then with water, and is dried to yield the desired product N-(4-nitro-6-ethoxy-2-pyridyl)-α-chloroacetamide.
