Reaction Steps

To a solution of 3-(4-methyl-1H-pyrazol-1-yl)-5-(trifluoromethyl)aniline (160 mg, 0.663 mmol) and 2-(4-(5-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)acetic acid (274 mg, 0.663 mmol) in pyridine (8 mL) was added T3P® (2111 mg, 3.32 mmol) in portions. Then 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)pyridin-3-yl)-2-fluorophenyl)-N-(3-(4-methyl-1H-pyrazol-1-yl)-5-(trifluoromethyl)phenyl)acetamide (200 mg, 0.263 mmol, 39.7% yield). 1H NMR (400 MHz, CD3OD): δ 8.24 (s, 1H), 8.06 (s, 1H), 7.96 (d, J=2.0 Hz, 1H), 7.87 (s, 1H), 7.74 (s, 1H), 7.57 (s, 1H), 7.48-7.42 (m, 3H), 7.40 (d, J=9.0 Hz, 3H), 6.91 (d, J=8.8 Hz, 2H), 5.37 (s, 2H), 4.18-4.13 (m, 2H), 3.86 (s, 2H), 3.79 (s, 3H), 2.16 (s, 3H), 1.43 (t, J=7.0 Hz, 3H). ES-LCMS: m/z 635.1 (M+H).
