Reaction Steps
A mixture of N-(((1S,2S)-2-(4-fluorophenyl)cyclopropyl)methyl)-2-hydrazinyl-3-(trifluoromethyl)pyridin-4-amine (0.38 g, 1.117 mmol) in EtOAc (3 mL) and THF (3 mL) and sat'd aqueous sodium carbonate (3 mL) was stirred as 3,3,3-trifluoropropanoyl chloride (0.213 g, 1.452 mmol) was added slowly. The mixture was stirred for 10 min. The reaction was diluted with EtOAc, washed with aqueous sodium bicarbonate, dried with brine, and concentrated. The crude product was purified by silica gel chromatography using 0-100% ethyl acetate/hexane as the eluent to give 3,3,3-trifluoro-N′-(4-((((1S,2S)-2-(4-fluorophenyl)cyclopropyl)methyl)amino)-3-(trifluoromethyl)pyridin-2-yl)propanehydrazide as an off-white solid (0.4 g, 71.6% yield). 1H NMR (400 MHz, CHLOROFORM-d) d 7.87 (d, J=6.3 Hz, 1H), 7.08-6.92 (m, 4H), 6.23 (d, J=6.3 Hz, 1H), 5.35 (d, J=3.8 Hz, 1H), 3.35-3.12 (m, 4H), 1.89 (dt, J=9.1, 4.9 Hz, 1H), 1.44-1.31 (m, 1H), 1.07 (dt, J=8.4, 5.5 Hz, 1H), 0.98 (dt, J=8.9, 5.5 Hz, 1H). LCMS M+1=451.1.
