Process for the preparation of frovatriptan and its enantiomer It relates to the compounds of formula [II-(R,S)] and formula [II-(S,R)], and to a process for their preparation which comprises: a) reacting an enantiomeric mixture containing a compound of formula [I-(R)] and a compound of formula [I-(S)] with a chiral agent in the presence of a solventmixture; b) isolating the compound of formula [II-(R,S)] or, alternatively, the compound of formula [II-(S,R)] from the corresponding diastereomericmixture; and c) optionally purifying them. It also relates to a process for the preparation of frovatriptan and its enantiomer from a compound of formula [II-(R,S)] or a compound of formula [II-(S,R)] respectively.
制备frovatriptan及其对映体的过程涉及到化合物的公式[II-(R,S)]和公式[II-(S,R)],以及制备它们的过程包括:a)在溶剂混合物的存在下,将含有公式[I-(R)]化合物和公式[I-(S)]化合物的对映体混合物与手性试剂反应;b)从相应的不对映异构体混合物中分离出公式[II-(R,S)]或者公式[II-(S,R)]化合物;c)可选地对其进行纯化。还涉及从公式[II-(R,S)]化合物或公式[II-(S,R)]化合物分别制备frovatriptan及其对映体的过程。
