Versuchsvorschrift

To a solution of 3-(2′,3′,4′,5′-tetrahydro-[1,1′-biphenyl]-4-yl)-1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazole (CB10) (3.11 g, 8.07 mmol) in diethyl ether (60 mL) was added meta-chloroperoxybenzoic acid (70%; 2.79 g, 11.3 mmol) slowly at 0° C. The reaction was stirred and allowed to gradually warm to room temperature, then stirring was continued for 18 hours. The solution was diluted in diethyl ether, washed with sodium bicarbonate, extracted with diethyl ether, washed with water, and extracted again with diethyl ether. The organics were dried, filtered, and concentrated providing the title compound as a white solid (2.5 g, 77%) which was used without further purification: 1H NMR (400 MHz, CDCl3) δ 8.58 (s, 1H), 8.20-8.11 (m, 2H), 7.84-7.77 (m, 2H), 7.52-7.46 (m, 2H), 7.39 (dt, J=8.0, 1.0 Hz, 2H), 3.12 (dd, J=3.1, 1.7 Hz, 1H), 2.34 (ddd, J=14.9, 8.5, 5.3 Hz, 1H), 2.09-1.95 (m, 2H), 1.74-1.45 (m, 4H), 1.42-1.28 (m, 1H); 19F NMR (376 MHz, CDCl3) δ −58.03; ESIMS m/z 402 ([M+H]+).
