Procedure

To a stirred solution of dimethyl aminomalonate hydrochloride (1.83 g, 10 mmol) in dichloromethane (30 mL) triethylamine (3 mL, 22 mmol) will be added at 0° C. 4-bromobenzoyl chloride (2.19 g, 10 mmol) will be slowly added the resulting solution will be allowed to stand at room temperature overnight. Water will be added and the organic layer will be separated and dried over anhydrous MgSO4. The evaporation of solvent will result in Int P.
