実験手順

A mixture of methyl 3-(cyclopropylmethoxy)-4-(methylsulfonamido)benzoate (1 g, 3.34 mmol), 2-bromoethanol (0.835 g, 6.68 mmol), and K2CO3 (0.923 g, 6.68 mmol) in CH3CN (12 ml) was heated at 110° C. under microwave irradiation for 12 hours. After cooling the solvent was evaporated and the residue was dissolved in EtOAc and filtered; the solvent was evaporated and the residue was purified by flash chromatography (eluent: EtOAc/petroleum ether 1/1) to give methyl 3-(cyclopropylmethoxy)-4-(N-(2-hydroxyethyl)methylsulfonamido)benzoate as a light brown oil (0.764 g, 2.225 mmol, 66.6% yield, /ESI+ 365.9 [MNa]+).
