実験手順

To a mixture of 3-fluoro-5-(4-fluoro-2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-4-methylbenzoic acid (50 mg, 0.114 mmol) and tert-butyl 3-amino-3-(pyrimidin-2-yl)azetidine-1-carboxylate hydrochloride (35.9 mg, 0.125 mmol) in DMF (1 ml) in a 25 ml round-bottomed flask was added PyBop (77 mg, 0.148 mmol) and then triethylamine (0.032 ml, 0.228 mmol). The reaction mixture was stirred overnight, and then diluted with water and extracted with EtOAc. The organic layer was further washed with water, dried over sodium sulphate and concentrated. The crude product was then purified by column chromatography (2% methanol in chloroform) to afford tert-butyl 3-(3-fluoro-5-(4-fluoro-2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-4-methylbenzamido)-3-(pyrimidin-2-yl)azetidine-1-carboxylate. Yield: 40 mg (52.4%). LCMS: (ES+) m/z observed=572.2 (M+H)+ of 4-fluoro-5-(3-fluoro-2-methyl-5-(3-(pyrimidin-2-yl)azetidin-3-ylcarbamoyl)phenyl)-2-(4-fluorophenyl)-N-methylbenzofuran-3-carboxamide
