The invention relates to a novel process for the preparation of chiral 2-(4-aminophenyl) morpholines of the formula
wherein R1 is hydrogen an amino protecting group.
The chiral 2-(4-aminophenyl) morpholines of the formula I are key intermediates for the preparation of compounds that have a good affinity to the trace amine associated receptors (TAARs).
本发明涉及一种制备手性 2-(4-氨基苯基)吗啉的新工艺,其式为
其中 R1 为氢和氨基保护基团。
式 I 的手性 2-(4-氨基苯基)吗啉是制备对痕量胺相关受体(TAAR)具有良好亲和力的化合物的关键中间体。
