Abstract

Disclosed is a ticagrelor monohydrate crystal form. There are two large endothermic peaks at 102±5°C and 136±5°C in the differential scanning calorimetry spectrum thereof, and the thermogravimetry spectrum displays the presence of one molecule of crystallization water. This crystal form has a good storage stability, and the water-solubility thereof is better than the anhydrous crystal form reported. The ticagrelor monohydrate is obtained by heating and dissolving ticagrelor in a mixed solvent of an organic solvent and water, then cooling, crystallizing, filtering, and drying it. The preparation method is easy to operate, the solvent thereof is environmentally friendly and controllable and thus is easy to recycle and reuse, therefore the method is suitable for industrial mass production. The ticagrelor monohydrate can be used for preparing drugs for treating/preventing thrombosis.

Abstract

The present invention provides a method of preparing cinacalcet hydrochloride. With the presence of inorganic alkali, heat and reflux (R)-1-Naphthylethylamin (Formula I compound ) and m-trifuoromethyl phenyl compound (Formula II compound) in an organic solvent till Formula II compound disappears, so as to obtain a cinacalcet reaction mixture. Obtain cinacalcet hydrochloride through post-processing. In Formula II, L is a halogen atom, trifluoromethanesulfonat (OMs), tosylate (OTs), and methanesulfonat (OTf). The present invention In the post-processing, (R)-1-Naphthylethylamin hydrochloride and cinacalcet hydrochloride are separated through simple operations such as pH control and extraction. (R)-1-Naphthylethylamin extracted and separated can be recycled and used to prepare a next batch of cinacalcet hydrochloride. For the present invention, the operations are simple, the post-processing is convenient, the yield is high, related substances in the prepared cinacalcet hydrochloride are low in content, and the quality is high. The method of present invention is suitable for industrial production and has a high application value.
