A Novel and Simple Synthesis of Ethers of Hydroxypyridines with Hexafluoropropan-2-ol via Diazotization of Aminopyridines and Aminoquinolines Under Acid-Free Conditions

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Herein, we report the first example of diazotization of aminopyridines and aminoquinolines with t-BuONO in hexafluoropropan-2-ol in the absence of acids or other initiators. For aminopyridines, this reaction is the first general route toward 2-, 3-, and 4-[(1,1,1,3,3,3-hexafluoropropan-2-yl)oxy]pyridines.
