Although not cited in this latter reference, it was apparantly possible to prepare, using DCC/HOBt, and to obtain a crystal structure of the HOBt amide of N-trityl methionine (Barlos, K.; Papaioannou, D.; Voliotis, S.; Prewo, R.; Bieri, J.H. J. Org. Chem. 1985, 50, 696-697), thereby dismissing the incorrect structure of a HOBt amide in the former reference.
