Procedure
The ester was prepared according to Procedure A using diethyl 2-methylmalonate (5.32 mL, 30.9 mmol), pyridine (3.33 mL, 41.2 mmol) and 4-chloro-3-fluoroaniline (3.00 g, 20.6 mmol). The residue was purified by column chromatography on silica gel (0-30% EtOAc/hexanes) to give ethyl 3-(4-chloro-3-fluorophenylamino)-2-methyl-3-oxopropanoate as a red oil. Mass Spectrum (ESI) m/e=274.1 (M+1).
