Procedure

To a solution of 4-(5-fluoro-6-(3-fluoroazetidine-1-carbonyl)pyridin-3-yloxy)-2,2-dimethyl-2,3-dihydrobenzofuran-6-carboxylic acid (1.360 g, 3.363 mmol), 3-amino-1-methyl-pyrazole (653 mg, 6.730 mmol), and triethylamine (0.94 ml, 6.730 mmol) in 20 mL of DCE was added HATU (2.56 g, 6.730 mmol). The mixture was stirred at 60° C. for 2 hr, quenched with water, and extracted with 3×CHCl3. The combined organic layer was washed with 2×H2O, dried with Na2SO4, and concentrated to provide an oil that was purified by SFC to give a white solid (874 mg, 54% yield). 1H NMR (400 MHz, CDCl3) δ 9.30 (s, 1 H) 8.20 (d, J=2.02 Hz, 1 H) 7.24-7.33 (m, 2 H) 7.15-7.22 (m, 1 H) 7.09 (dd, J=10.86, 2.27 Hz, 1 H) 6.82 (d, J=2.27 Hz, 1 H) 5.37 (d, J=56.84 Hz, 1 H) 4.62-4.79 (m, 1 H) 4.53 (dd, J=12.13, 1.77 Hz, 2 H) 4.27-4.42 (m, 1 H) 3.80 (s, 3 H) 2.92 (s, 2 H) 1.50 (s, 6 H); LCMS for C24H23F2N5O4 m/z 484.20 (M+H)+.
