1-Trifluoromethyl Epoxy Ethers. Effect of Hexafluoro-2-propanol on Reactions with Secondary Aromatic Amines: Synthesis of 3-Trifluoromethyl Indole Derivatives
Trifluoromethyl epoxyethers 1 and 2 reacted with aromatic amines in hexafluoro-2-propanol at room temperature providing trifluoromethyl indolinols 3 and 4 in excellent isolated yields. 3-Trifluoromethyl indoles 9 and 10 could be prepared by treatment of indolinols with SOCl(2).
