Added at the eleventh hour: A method for the late-stage directed amination of benzoicacids is presented. It allows rapid access to both small amino-functionalized analogues and large conjugates, including PROTACs, peptide conjugates and probes for chemical biology. Selection of the right catalyst and reagent enabled the use of high-throughput experimentation and automation.
