Disclosed is a process for the synthesis of the active ingredients ospemifene and fispemifene which comprises reacting phenol 4 with an alkylating agent X- CH2CH2-Y of formula 7, wherein X is a leaving group and Y is the -(OCH2CH2)nOH group wherein n is zero or 1; or X and Y, taken together, represent an oxygen atom; to give ospemifene or fispemifene of formula 8.
本发明揭示了一种合成活性成分ospemifene和fispemifene的方法,该方法包括将
苯酚4与
化学式7中的烷基化剂X- CH2CH2-Y反应,其中X是离去基团,Y是-(OCH2CH2)nOH基团,其中n为零或1;或X和Y一起表示一个氧原子,以得到
化学式8中的ospemifene或fispemifene。
