Reaction Steps

To a solution of 3-(2,2,2-trifluoroethoxymethyl)benzofuran-2-carboxylic acid (38 mg, 0.139 mmol) in anhydrous DMF was added EDC.HCl (37 mg, 0.195 mmol) and HOBt.H2O (26 mg, 0.195 mmol). After 60-90 min., methyl-(4-(2-ethoxyamine))benzoate hydrochloric salt (32 mg, 0.139 mmol) and triethylamine (23 μL, 0.167 mmol) were added and the reaction mixture was stirred for 1-2 h. The reaction mixture was diluted with EtOAc and washed twice with saturated NaHCO3(aq,) and the organic extract was concentrated to give methyl 4-{2-[3-(2,2,2-trifluoroethoxymethyl)benzofuran-2-yl-carbonylamino]ethoxy}-benzoate, which was then used without further purification.
