As used herein the term "room temperature" refers to a temperature of about 25°C to about 35°C. According to one aspect of the present invention, there IS provided a novel process for the preparation of rilpivirine, which comprises: a) condensing the (E)-3-( 4-amino-3,5-dimethylphenyl)acrylonitrile hydrochloride with 4-( 4-chloropyrimidin-2-ylamino )benzonitrile m the presence of Nmethylpyrrolidone; b) heating the contents obtained in step (a) at about 75 to 95°C to obtain a solution; c) cooling the solution obtained in step (b) at below 35°C; d) adding water to the reaction mass; and e) isolating rilpivirine. The reaction in step (b) may preferably be heated to 100 to 110°C. Step (c) may preferably be carried out at room temperature. Rilpivirine may be isolated in step (e) by the methods known such as Filtration or centrifugation.
在这里使用的术语“室温”指的是大约25°C到大约35°C的温度。根据本发明的一个方面,提供了一种制备利匹韦林的新工艺,该工艺包括:a)将(E)-3-(4-氨基-3,5-二甲基苯基)丙烯腈盐酸盐与4-(4-氯嘧啶-2-基氨基)苯腈在N-甲基吡咯烷酮的存在下进行缩合;b)将步骤(a)中获得的物质加热至大约75至95°C以获得溶液;c)将步骤(b)中获得的溶液在35°C以下冷却;d)向反应物中加水;e)分离出利匹韦林。步骤(b)中的反应优选加热至100至110°C。步骤(c)优选在室温下进行。利匹韦林可以通过步骤(e)中已知的方法如过滤或离心进行分离。
