Provided is a process for preparing Voriconazole represented by Chemical Formula 1. More particularly, the process for preparing Voriconazole of Chemical Formula 1 includes: carrying out the Reformatsky-type coupling reaction between a ketone derivative of Chemical Formula 4 and a pyrimidine derivative of Chemical Formula 5 to obtain a compound of Chemical Formula 3; reacting the substituents halo and oxysulfonyl with a hydrogen donor to obtain racemic Voriconazole of Chemical Formula 2; and carrying out optical isolation of the racemic Voriconazole by adding an adequate optically active acid thereto to obtain Voriconazole having high optical purity with high cost-efficiency and high yield.
提供的是一种制备化学式1所代表的伏立康唑(Voriconazole)的过程。更具体地,制备化学式1的伏立康唑的过程包括:在化学式4的酮衍生物和化学式5的嘧啶衍生物之间进行Reformatsky型偶联反应,以获得化学式3的化合物;将卤素和氧磺酰基的取代基与氢供体反应,以获得化学式2的外消旋伏立康唑;通过向外消旋伏立康唑中添加适量的光学活性酸进行光学隔离,以获得具有高光学纯度、高成本效益和高产率的伏立康唑。
