An efficient synthesis of 1-arylindazole-3-carboxamides using nitrile imines, isocyanides and 2-hydroxymethylbenzoic acid, followed by a chemoselective Buchwald-Hartwig intramolecular cyclization

A convergent and efficient two-step synthesis of pharmaceutically relevant 1-arylindazole-3-carboxamides is reported. These molecules have been obtained in good to excellent yields (up to 98%) starting from a strategic reaction between isocyanides, 2-iodo
