专利号:US-11827598-B1 优先权日:2022-07-15 标 题:Preparation method of tofacitinib citrate 发明人:HSU YAO-LUNG; HSIEH KUANG-CHAN; CHENG HUI-WEN; Yang zong-han 权利人:CHUNGHWA CHEMICAL SYNTHESIS & BIOTECH CO LTD 摘要:The present disclosure provides a preparation method of tofacitinib citrate, which comprises the following steps: passing an intermediate TOF-2 into hydrogen at a normal pressure in the presence of a catalyst to obtain an intermediate TOF-3; in the presence of a solvent and a base, under a reduced pressure of −490 mmHg to −760 mmHg, and at a temperature of 10° C. to 25° C., reacting TOF-3 with ethyl cyanoacetate to generate an intermediate TOF-4; heating and dissolving TOF-4 and citric acid in a solvent, and performing separation by cooling to obtain tofacitinib citrate. The present disclosure obtains tofacitinib citrate with high yield, high purity and low impurities by changing a gas flow rate and a reaction temperature and pressure of a hydrogenation reaction. Therefore, the preparation method is suitable for industrial production.
