Application
[3+2] Cycloaddition of Arynes with CF3CHN2 for the Synthesis of 3-Trifluoromethyl-1H-indazoles
Typical Procedure:
To a 10 mL sealed tube backfilled with Ar is added 2-(trimethylsilyl)phenyl triflate (59.7 mg, 0.2 mmol), CsF (72.9 mg, 0.48 mmol), TEBAC (136.7 mg, 0.6 mmol) and CF3CHN2 (88 mg, 4 mL, 0.2 M, 4.0 eq.) in THF with vigorous stirring at 25 °C for 24 h. The reaction mixture is poured into saturated brine (15 mL) and extracted with ethyl acetate (15 mL×3). The combined organic layers are dried over MgSO4 and concentrated under reduced pressure. The residue is purified by flash chromatography on silica gel to afford the desired 3-trifluoromethylindazole.
