Versuchsvorschrift

To a solution of 2-(4-(5-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)acetic acid (100 mg, 0.243 mmol) and 3-(1-methyl-1H-pyrazol-4-yl)-5-(trifluoromethyl)aniline (58.6 mg, 0.243 mmol) in pyridine (2 mL) was added T3P® (0.5 mL, 0.243 mmol) at 27° C. under N2. The mixture was stirred at 27° C. for 30 min. LCMS showed the reaction was completed. Then the mixture was put onto ice (5 g). The mixture was concentrated to give the residue. The residue was purified by preparative TLC (DCM/MeOH=10:1, Rf=0.6) to yield a light yellow solid of 2-(4-(5-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)-N-(3-(1-methyl-1H-pyrazol-4-yl)-5-(trifluoromethyl)phenyl)acetamide (138 mg, 0.217 mmol, 89% yield): 1H NMR (400 MHz, CD3OD) δ 8.09-7.93 (m, 2H), 7.87-7.76 (m, 2H), 7.69-7.52 (m, 2H), 7.49-7.33 (m, 4H), 7.23 (dd, J=7.8, 16.4 Hz, 2H), 6.91 (d, J=7.9 Hz, 1H), 6.72 (d, J=8.4 Hz, 1H), 5.38-5.15 (m, 2H), 4.15 (d, J=7.1 Hz, 2H), 3.94-3.60 (m, 8H), 1.42 (t, J=6.8 Hz, 3H). ES-LCMS m/z 635 (M+H).
