Processes For The Preparation Of Optically Active Intermediates

摘要

This invention relates to processes for the production of optically active 2-(disubstituted aryl)cyclopropylamine compounds and optically active 2-(disubstituted aryl) cyclopropane carboxamide compounds which are useful intermediates for the preparation of pharmaceutical agents, and in particular the compound [1S-(1α,2α,3&bgr;(1S*,2R*),5&bgr;]-3-[7-[2-(3,4-difluorophenyl)-cyclopropyl]amino]-5-(propylthio)-3H-1,2,3-triazolo[4,5-d]pyrimidin-3-yl)-5-(2-hydroxyethoxy)-cyclopentane-1,2-diol.
