Procedure
The ester was prepared according to procedure A using diethyl 2-methylmalonate (6.18 mL, 36.0 mmol), pyridine (3.88 mL, 47.9 mmol) and 5-fluoro-2-methyl aniline (3.00 g, 23.97 mmol). Heating continued for 4 days. The residue was purified by column chromatography on silica gel (0-30% EtOAc/hexanes) to give ethyl 3-(5-fluoro-2-methylphenylamino)-2-methyl-3-oxopropanoate as a tan solid. Mass Spectrum (ESI) m/e=254.2, (M+1).
