Procedure

To a stirred solution of (E)-2-(3-amino-1H-1,2,4-triazol-1-yl)-5-(4,4,4-trifluoro-3-(3,4,5-trichlorophenyl)but-1-enyl)benzonitrile (0.15 g, 0.31 mmol) in DCM at 0° C., were added triethylamine (0.1 g, 1 mmol) and cyclopropylcarbonyl chloride (0.04 g, 0.38 mmol) and the reaction mixture was stirred for 1 h at 0° C. The reaction mixture was diluted with DCM and washed with water and brine and dried over Na2SO4. Concentration under reduced pressure and purification by column chromatography (SiO2, 100-200 mesh) afforded the title compound as a solid (66 mg, 34%): mp 109-112° C.; 1H NMR (300 MHz, DMSO-d6) δ 10.94 (br s, 1H), 8.36 (s, 1H), 8.08 (m, J=8.4 Hz, 1H), 7.91 (s, 2H), 7.84 (d, J=8.4 Hz, 1H), 7.13 (dd, J=15.6, 9.2 Hz, 1H), 6.87 (d, J=15.6 Hz, 1H), 4.92 (m, 1H), 1.99 (br s, 1H), 0.82 (s, 4H); ESIMS m/z 540.04 ([M+H]+); IR (thin film) 3233, 2233, 1699, 1114, 807 cm−1.
