The first method for the direct one-pot transformation of aminopyridines into pyridinyl trifluoromethanesulfonates is developed. The procedure involves diazotization of aminopyridines with sodium nitrite in a DMSO paste in the presence of trifluoromethanesulfonic acid. (C) 2014 Elsevier Ltd. All rights reserved.
