Reaction Steps

(E)-1-(Pyridin-2-yl)-N-(4-(4,4,4-trifluoro-3-(3,4,5-trichlorophenyl)but-1-en-1-yl)-2-(trifluoromethyl)benzyl)methanamine (0.27 g, 0.05 mmol) was taken up in CH2Cl2 (3 mL). To this was added TEA (0.14 mL, 0.1 mmol). The reaction mixture was stirred for 10 min After 10 min, the reaction mixture was cooled to 0° C., and cyclopropylcarbonyl chloride (0.08 mL, 0.075 mmol) was added. The reaction mixture was stirred at ambient temperature for 1 h and then was washed with water and satd aq NaHCO3 solution. The organic layer was dried over anhydrous Na2SO4 and evaporated to obtain pale yellow gummy material (0.15 g, 50%): 1H NMR (400 MHz, CDCl3) δ 8.58 (d, J=4.6 Hz, 1H), 7.74 (m, 1H), 7.62 (m, 2H), 7.52 (m, 1H), 7.4 (s, 2H), 7.3 (m, 1H), 7.2 (m, 2H), 6.60 (d, J=16.0 Hz, 1H), 6.38 (dd, J=16.0, 8.0 Hz, 1H), 5.02 (s, 1H), 4.8 (s, 1H), 4.8 (d, J=10 Hz, 2H), 4.10 (m, 1H), 1.8 (m, 1H), 1.2 (m, 2H), 0.6 (m, 2H); ESIMS m/z 620.86 ([M−H]−); IR (thin film) 1645, 1115, 808 cm−1.
