| description | Disclosed is a method for preparing a canagliflozin form. The method comprises the following steps: adding canagliflozin into an organic solvent and dissolving same, then distilling into a certain amount of an oil; then, adding an anti-solvent to the oil, stirring same with a precipitated solid, cooling, filtering, and drying to obtain the canagliflozin amorphous form. The preparation method has the characteristics of a low solvent ratio, a high yield, a simple operation, easy recovery, less three wastes and good producibility, with the resulting product having a stable quality, good fluidity, and being suitable for the preparation of formulations, etc., and the preparation process is easy to apply to large commercial production, and has a high value in terms of promotion and application. |
