Reaction Steps
A solution of 1 g of 2,2-dimethyl-3-hydroxymethyl-4-(1,2-dihydro-2-oxo-1-pyridyl)-6-nitro-3-chromene in 25 ml of methanol is hydrogenated on 0.5 g of 5% Pd-C at 20° C. and at 1 bar until hydrogenation is complete. The mixture is filtered, evaporated and 2,2-dimethyl-3-hydroxymethyl-4-(1,2-dihydro-2-oxo-1-pyridyl)-6-amino-3-chromene is obtained.
