Kind Code:
A1
Abstract:
The present invention relates to a crystalline form of (2-(3,4-dimethoxyphenyl)-5-(3-methoxypropyl)benzofuran) and a method for preparing the same. The crystalline form of (2-(3,4-dimethoxyphenyl)-5-(3-methoxypropyl)benzofuran) according to the present invention has excellent physicochemical properties, such as long-term storage stability and non-hygroscopicity. In addition, the crystalline form according to the present invention has a high purity of 96% to 99%, and thus can be industrialized for mass production even without performing the existing column purification for removing impurities and improving purity. Therefore, the processing time can be shortened and thus the manufacturing cost can be lowered.
