Procedure

A solution of 1 g of 2,2-dimethyl-3-hydroxymethyl-4-(1,2-dihydro-2-oxo-1-pyridyl)6-amino-3-chromene in 15 ml of formic acid and 1 ml of pyridine is boiled for 24 hours and evaporated. After customary working up, 2,2-dimethyl-3-hydroxymethyl-4-(1,2-dihydro-2-oxo-1-pyridyl)-6-formamido-3-chromene is obtained.
