Reaction Steps

1-Cyclohexyl-3-hydroxy-2-methylpyrid-4-one was prepared by dissolving 10.0 g of 3-hydroxy-2-methylpyr-4-one (Maltol) and 3 equivalents (~27 ml) of cyclohexylamine (99+ %) in 200 ml of water. Decolorizing charcoal was added and the mixture was stirred for 0.5 hours. The aqueous mixture was filtered through a course frit then concentrated in vacuo, leaving an oily residue. Crystallization from hot water yielded crystals of the desired product. m.p. 199° C.
