Procedure

A mixture of 1 g of 2,2-dimethyl-4-(1-methyl-1,2-dihydro-2-oxo-3-pyridyl)-6-amino-3-chromanol, 10 ml of acetic anhydride and 10 ml of pyridine is allowed to stand at 20° for 24 hours. The mixture is evaporated, worked up in the customary manner and 2,2-dimethyl-4-(1-methyl-1,2-dihydro-2-oxo-3-pyridyl)-6-acetamido-3-chromanol is obtained.
