Procedure

To a mixture of 5-(4-fluoro-2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-2-methoxy-4-methylbenzoic acid (50 mg, 0.111 mmol) and tert-butyl 3-amino-3-(pyrimidin-2-yl)azetidine-1-carboxylate hydrochloride (31.8 mg, 0.111 mmol) in DMF (1 ml) in a 25 ml round-bottomed flask was added PyBOP (69.2 mg, 0.133 mmol) and then triethylamine (0.046 ml, 0.332 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-(5-(4-fluoro-2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-2-methoxy-4-methylbenzamido)-3-(pyrimidin-2-yl)azetidine-1-carboxylate. Yield: 40 mg (53%). LCMS: (ES+) m/z observed=584.2 (M+H)+ of 4-fluoro-2-(4-fluorophenyl)-5-(4-methoxy-2-methyl-5-(3-(pyrimidin-2-yl)azetidin-3-ylcarbamoyl)phenyl)-N-methylbenzofuran-3-carboxamide
