Objective To search for a facile synthetic route for synthesis of target compound 4-(6-deoxy-β-D-glucopyranosyl)-1- methosyl-2-[(trans-4-n-propylcyclohexyl)methyl] benzene and to study its polymorphic characteristics. Methods A phenyl bromide fragment and 6-deoxygluconolactone fragment were used as starting materials to synthesize the target compound. Polymorph of target compound was prepared from organic mixed solvents and aqueous mixed solvents. and was characterized by powder X ray diffraction (PXRD), and thermogravimetric analysis coupled with differential thermal analysis (TG-DTA), and the preliminary stability properties of the polymorph was also studied. Results The total yield of target compound was 74%. The same polymorph of the target compound was obtained by the above methods, and was stable to light, heat, and moisture. Conclusion A facile synthetic route for synthesis of target compound is developed, which has the advantages of simple operating procedure, easy post-processing and high yield, and a stable polymorph of target compound is obtained.
