The reduction of methionine sulfoxide with Bu 4 NBr in TFA is reported. The use of this reagent in conjunction with Fmoc chemistry-based acidolytic cocktails and the short reaction times that are needed for sulfoxide reduction (5 min) are the main advantages of this method, which is compatible with
