To a mixture of 2-(4-(5-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)acetic acid (100 mg, 0.243 mmol) in pyridine (10 mL) were added 3-(2H-tetrazol-5-yl)-5-(trifluoromethyl)aniline (55.7 mg, 0.243 mmol) and T3P® (EA solvate) (220 mg, 0.346 mmol). The mixture was stirred at 20° C. for 1 h. LCMS showed the reaction was finished. The reaction was quenched with ice-water. The mixture was concentrated to give crude product, which was purified by TLC to give N-(3-(2H-tetrazol-5-yl)-5-(trifluoromethyl)phenyl)-2-(4-(5-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)acetamide (75 mg, 0.104 mmol, 42.9% yield): 1H NMR (400 MHz, CD3OD-d4) δ 8.62 (d, J=4.4 Hz, 2H), 8.04 (d, J=1.5 Hz, 1H), 7.94 (s, 1H), 7.61 (dd, J=6.1, 7.8 Hz, 2H), 7.38 (d, J=8.6 Hz, 3H), 6.92-6.85 (m, 3H), 5.35 (s, 2H), 4.15 (d, J=6.8 Hz, 2H), 3.77 (s, 2H), 3.38-3.33 (m, 3H), 1.30-1.18 (m, 3H). ES-LCMS m/z 623 (M+H).
