실험 절차

To a 20 mL vial, 1-(o-tolyl)thiourea (0.096 g, 0.58 mmol) and cesium carbonate (0.22 g, 0.68 mmol) were charged as solids. Then 3-(3-(2-isocyanatoethyl)phenyl)-1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazole (CA44) (0.20 g, 0.52 mmol) in acetonitrile (4.0 mL) was added. The reaction was allowed to stir at room temperature overnight. The reaction mixture was diluted with dichloromethane and filtered through a phase separator. The filtrate was purified by flash column chromatography using 0-50% ethyl acetate/hexanes as eluent followed by flash column chromatography using 10-50% ethyl acetate/B, where B=1:1 dichloromethane/hexanes, as eluent to provide the title compound as a white solid (0.11 g, 37%): 1H NMR (400 MHz, DMSO-d6) δ 12.01 (s, 1H), 10.12 (s, 1H), 9.42 (s, 1H), 8.13-8.05 (m, 2H), 8.04-7.96 (m, 2H), 7.66-7.54 (m, 3H), 7.54-7.46 (m, 1H), 7.39 (dt, J=7.7, 1.5 Hz, 1H), 7.29-7.24 (m, 1H), 7.24-7.14 (m, 2H), 7.03 (t, J=5.6 Hz, 1H), 3.46 (q, J=6.6 Hz, 2H), 2.96-2.84 (m, 2H), 2.20 (s, 3H); 19F NMR (376 MHz, DMSO-d6) δ −56.96; ESIMS m/z 541 ([M+H]+), 539 ([M−H]−).
