The present invention relates to a novel method for preparing a 5,7-difluorochroman-4-one derivative. The preparation method according to the present invention allows industrial mass production by using a generally usable reagent and solvent requiring no separate refinement process, having low production costs, and being under no environmental regulation and thus allows a 5,7-difluorochroman-4-one derivative to be efficiently produced. La présente invention concerne un nouveau procédé de préparation d'un dérivé de 5,7-difluorochroman-4-one. Le procédé de préparation selon la présente invention permet la production industrielle de masse en utilisant d'une manière générale un réactif et un solvant utilisables ne nécessitant pas de processus de raffinage distinct, ayant de faibles coûts de production, et n'étant soumis à aucune réglementation sur l'environnement, ce qui permet la production efficace d'un dérivé de 5,7-difluorochroman-4-one. 본 발명은 5,7-디플루오로크로만-4-온 유도체의 신규한 제조방법에 관한 것이다. 본 발명의 제조방법은 별도의 정제 공정이 필요하지 않고 낮은 제조 원가를 가지며, 환경 규제도 받지 않는 통상적으로 사용 가능한 시약과 용매를 사용하여 산업적으로 대량생산이 가능하여, 5,7-디플루오로크로만-4-온 유도체를 효과적으로 생산할 수 있다.
