Reaction Steps

To a mixture of 3-fluoro-5-(4-fluoro-2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-4-methylbenzoic acid (0.050 g, 0.114 mmol, 1.0 eq) and 3-(pyridin-2-yl)oxetan-3-amine 2HCl (0.03 g, 0.134 mmol, 1.2 eq) in DMF at 0° C. was added TEA (0.15 ml, 1.08 mmol, 9 eq) and BOP reagent (0.06 g, 0.136 mmol, 1.2 eq). The reaction mixture was stirred as rt overnight. The reaction mixture was diluted with water and extracted with EtOAc. The organic layer was washed with brine, dried over Na2SO4 filtered and the filtrate concentrated. The crude product was purified by preparative HPLC. Yield: 0.010 g (15.3%).
