The present invention provides novel and advantageous processes for preparing and purifying chemical compounds such as pharmaceuticals. The processes comprise a nucleophilic substitution reaction with a moiety X wherein the leaving group L of a substrate S in the reaction is covalently attached to a purification moiety M. This concept offers a convenient and lime-saving way to purity the desired product S-X from non-reacted precursors S-L-M and by-products L-M.
本发明提供了一种新颖和有利的制备和纯化
化学化合物,如药物的方法。该方法包括使用一个官能团X进行亲核取代反应,其中反应底物S的离去基团L共价地连接到纯化官能团M上。这个概念提供了一种方便和节省时间的方法,以从未反应的前体S-L-M和副产物L-M中纯化所需的产品S-X。
