Procedure

To a stirred solution of 2-(4-Amino-3-hydroxy-phenyl)-propionic acid (1.02 g) in H2O was added BrCN (648 mg) at room temperature. After stirred for 40 h at room temperature, the reaction mixture was neutralized with 30% aq. NaOH to pH 6-7 and then stirred for 1 hour. The solid was filtered, washed with water and dried under reduced vacuum to afford the product as yellow solid. (760 mg, 65.5%)
