The invention relates to a method of preparation of 2-amino-2-[2-(4-octylphenyl)- ethyl]propane-1,3-diol (I), comprising opening of the aziridine ring of the intermediates (LVI) by the treatment with organometallic compounds, preferably the Grignard reagents (LVII), producing the key intermediates (LVIII) or (LIX). Another object of the invention is use of the compounds (LVIII) and (LIX) for preparation of fingolimod.
这项发明涉及一种制备2-氨基-2-[2-(4-辛基苯基)-乙基]丙烷-1,3-二醇(I)的方法,包括通过与有机金属化合物(优选为格氏试剂(LVII))处理中间体(LVI)来打开环氮丙烷环,生成关键中间体(LVIII)或(LIX)。该发明的另一个目的是利用化合物(LVIII)和(LIX)来制备非格列酮。
