The present invention provides a method for producing hydridone that is simple in operation, mild in reaction conditions, short in reaction time, high in yield, safer and suitable for large-scale production. The present invention performs purification by dissolving and decolorizing an intermediate compound of formula II with ethyl acetate and activated carbon, and is more efficient than simply performing reconstitution, and the yield of the intermediate compound obtained in a short time is high. Good decolorization effect. [Selection figure] None本発明は、操作が簡単で、反応条件が温和で、反応時間が短く、収率が高く、より安全で大規模生産に適する、ヒドロニドンの製造方法を提供する。本発明は、酢酸エチルと活性炭素で中間体の式II化合物を溶解脱色して精製を行い、単に再結成を行うより効率が高く、短時間で得られる中間体の化合物の収率が高く、脱色効果が良い。【選択図】なし
