An ammonia solution is added to a solution of maltol dissolved in hot distilled water. The pH of this solution is adjusted to 9.8 by the addition of HCl solution. The mixture is kept under reflux overnight and then decolorized with activated charcoal. The solvent is removed under reduced pressure. The white product is obtained upon recrystallization from hot water.
