Reaction Steps

A mixture of 1 g of 2,2-dimethyl-3-hydroxymethyl-4-(1,2-dihydro-2-oxo-1-pyridyl)-6-amino-3-chromene, 10 ml of acetic anhydride and 10 ml of pyridine is allowed to stand at 20° C. for 24 hours. The mixture is evaporated, and customary working up gives 2,2-dimethyl-3-hydroxymethyl-4-(1,2-dihydro-2-oxo-1-pyridyl)-6-acetamido-3-chromene.
