Provided herein is a novel process for the preparation of phenylcyclopropylamine derivatives, which are useful intermediates in the preparation of triazolo[4,5-d]pyrimidine compounds. Provided particularly herein is a novel, commercially viable and industrially advantageous process for the preparation of a substantially pure ticagrelor intermediate, trans-(1R,2S)-2-(3,4-difluorophenyl)-cyclopropylamine. The intermediate is useful for preparing ticagrelor, or a pharmaceutically acceptable salt thereof, in high yield and purity.
本文提供了一种新颖的制备苯基环丙胺衍生物的过程,这些衍生物在三唑并[4,5-d]嘧啶化合物的制备中是有用的中间体。特别提供了一种新颖的、商业可行且在工业上具有优势的过程,用于制备一种基本纯净的替卡格雷中间体,即trans-(1R,2S)-2-(3,4-二氟苯基)-环丙胺。该中间体可用于高产率和纯度地制备替卡格雷或其药学上可接受的盐。
