Novel crystalline form of enavogliflozin, and preparation method therefor.

Abstract

The present invention relates to a novel crystalline form of enavogliflozin, and a preparation method therefor. The novel crystalline form of enavogliflozin, according to the present invention, has thermodynamic stability and a hygroscopic property that are superior to those of a conventionally reported crystalline form of enavogliflozin, and thus has excellent long-term storage and pharmaceutical stability. In addition, the time to reach Cmax is shorter than that of the conventionally reported crystalline form of enavogliflozin such that drug effects can be rapidly exhibited, and thus the present invention can be effectively used.
