Reaction Steps

To a yellow solution mixture of 3-fluoro-5-(4-fluoro-2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-4-methylbenzoic acid (30 mg, 0.068 mmol) and 3-(pyrimidin-2-yl)oxetan-3-amine hydrochloride (12.5 mg, 0.067 mmol) in DMF (1 ml) in a 25 mL round-bottomed flask was added PyBOP (50 mg, 0.096 mmol), followed by TEA (0.1 ml, 0.717 mmol), and the reaction mixture was stirred for overnight. Ice cooled water was added to the reaction mixture, which was then stirred for 10-15 min. at 0° C. Precipitation was observed. The solid was collected by filtration, washed with cold water, and then dissolved in dichloromethane. The organic was dried over Na2SO4, filtered and concentrated. The crude product was purified by preparative HPLC. Yield (10 mg, 25%).
