Versuchsvorschrift

Add bromine (28 μL, 0.54 mmol) to a mixture of 1-[1-(3,5-bis-trifluoromethyl-benzyl)-5-pyridin-3-yl-1H-[1,2,3]triazol-4-yl]-3-(2-chloro-phenyl)-propane-1,3-dione (256 mg, 0.463 mmol) in 1:1 CH2Cl2:H2O (4 mL). Stir mixture at RT for 30 min, then dilute with additional CH2Cl2 (20 mL) and wash with NaHCO3 (20 mL). Dry, filter, and concentrate the organic layer to give the title compound (287 mg, 98%). MS (IS) 553.2 (M+1), MS (ES−) 551.2 (M−1). 1HNMR (400 MHz, CDCl3): δ 7.80 (m, 1H), 8.53 (m, 1H), 7.85 (m, 2H), 7.63 (m, 1H), 7.46 (m, 7H), 7.04 (s, 1H), 5.60 (m, 2H).
