Reaction Steps

To a solution of 3-(3-methyl-1H-pyrazol-1-yl)-5-(trifluoromethyl)aniline (250 mg, 1.036 mmol) and 2-(4-(5-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)acetic acid (429 mg, 1.036 mmol) in pyridine (5 mL) was added T3P® (3298 mg, 5.18 mmol) in portions. The mixture was stirred at 16° C. for 1 h. LCMS analysis showed the starting material disappeared. 10 mL of water was added dropwise into the reaction solution and then the mixture was filtered. The filter cake was washed with water (20 mL) and dried in vacuo to afford pure product 2-(4-(5-ethoxy-6-((4-methoxybenzyl)oxy)pyridine-3-yl)-2-fluorophenyl)-N-(3-(3-methyl-1H-pyrazol-1-yl)-5-(trifluoromethyl)phenyl)acetamide (280 mg, 0.357 mmol, 34.5% yield). 1H NMR (400 MHz, CD3OD): δ 8.25 (s, 1H), 8.15 (d, J=2.6 Hz, 1H), 7.96 (d, J=2.0 Hz, 1H), 7.85 (s, 1H), 7.75 (s, 1H), 7.50-7.43 (m, 3H), 7.41 (d, J=9.0 Hz, 3H), 6.92 (d, J=8.8 Hz, 2H), 6.36 (d, J=2.4 Hz, 1H), 5.37 (s, 2H), 4.18-4.13 (m, 2H), 3.86 (s, 2H), 3.79 (s, 3H), 2.34 (s, 3H), 1.43 (t, J=7.0 Hz, 3H). ES-LCMS: m/z 635.1 (M+H).
