実験手順
To a mixture of 3-(4-fluoro-2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-4-methylbenzoic acid (60 mg, 0.142 mmol) and tert-butyl 3-amino-3-(pyrimidin-2-yl)azetidine-1-carboxylate hydrochloride (40.8 mg, 0.142 mmol) in DMF (1 ml) was added PyBOP (74.1 mg, 0.142 mmol) and triethylamine (0.020 ml, 0.142 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-(4-fluoro-2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-4-methylbenzamido)-3-(pyrimidin-2-yl)azetidine-1-carboxylate Yield: 55 mg (59%). LCMS: (ES+) m/z observed=554.2 (M+H)+ of 4-fluoro-2-(4-fluorophenyl)-N-methyl-5-(2-methyl-5-(3-(pyrimidin-2-yl)azetidin-3-ylcarbamoyl)phenyl)benzofuran-3-carboxamide.
