Procedure

To a solution of ethyl 2-(2-bromophenyl)-3-hydroxyacrylate (1 g, 3.88 mmol) in methanol (10 mL) was added o-toluidine (0.416 g, 3.88 mmol) via syringe at room temperature. After being stirred for 18 hours at the same temperature, solvent was removed under reduced pressure to give the crude product of ethyl 3-(o-toluidino)-2-(2-bromophenyl)acrylate (1.326 g, 95%), which was used in the next step without further purification. LRMS (M+H+) m/z: calcd 359.05. found 359.
