Patents
International Publication WO 2007/072146 describes a process for preparing 5,7-difluorochroman-4-ol using 5,7-difluorochroman-4-one as a starting material. However, the production process described in the patent has a low optical stereoselectivity of 86% ee in the primary crystallization process and it is stated that a purification process is necessarily required to increase optical stereoselectivity. For this reason, the process described in the patent has a high production cost and a very low yield of 58% despite the additional purification process. In addition, there is a problem that column chromatography on silica gel is used for the primary solidification separation, which is not suitable for the mass production process.
