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 (0.1 g, 0.21 mmol) in DCM at RT, was added cyclopropylcarbonyl chloride (0.045 g, 0.42 mmol) and the reaction mixture was stirred for 2 h at RT. The reaction mixture was diluted with DCM and washed with water and brine and dried over Na2SO4. Concentration under reduced pressure and purification by preparative HPLC afforded the title compound as a solid (0.09 g, 79%): mp 104-107° C.; 1H NMR (300 MHz, CDCl3) δ 8.78 (s, 2H), 7.83 (s, 1H), 7.80 (m, 2H), 7.42 (s, 2H), 6.65 (d, J=16.4 Hz, 1H), 6.51 (dd, J=7.6, 8.0 Hz, 1H), 4.17 (m, 1H), 2.16 (m, 2H), 1.25 (m, 4H), 1.00 (m, 4H); ESIMS m/z 609.98 ([M+H]+); IR (thin film) 2234, 1714, 1114, 807 cm−1.
