A NOVEL AND SIMPLE SYNTHESIS OF ETHERS OF HYDROXYPYRIDINES WITH HEXAFLUOROPROPAN-2-OL VIA DIAZOTIZATION OF AMINOPYRIDINES AND AMINOQUINOLINES UNDER ACID-FREE CONDITIONS

Abstract
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.
Keywords
