A new and improved synthetic route to an intermediate in the synthesis of the phosphinate ester GSK2248761A is described. In the key step, we describe the first process-scale example of a palladium-catalyzed phosphorus–carbon coupling to give the e

Amidation of indole 2-carboxylate 1 with ammonia gas via the imidazolide 2 gave GSK2248761A API 3, which was in development for the treatment of HIV. Three significant impurities, namely the phosphinic acid 4, the N-acyl urea 8, and the indoloyl carb

ortho-Arylation of ortho-substituted benzoic acids is a challenging process due to the tendency of the reaction products toward Pd-catalyzed protodecarboxylation. A simple method for preventing decarboxylation in sterically hindered benzoic acids is
