To a suspension of NaH (32 mg, 60% wt. dispersion in mineral oil, 0.80 mmol) in DMF (0.5 mL) at room temperature was added malondianilide (169 mg, 0.67 mmol). The solution was stirred for 20 min and a solution of methyl 6-fluoronicotinate (129 mg, 0.62 mmol) in DMF (1 mL) was added. The reaction mixture was heated to 100° C. for 1 h, cooled to room temperature, and diluted with CH2Cl2 and water. The aqueous phase was extracted with CH2Cl2 (3×) and the combined extracts were washed with brine (1×), dried over MgSO4, filtered, and concentrated. Purification by reverse phase HPLC (40% to 90% MeCN in water) gave methyl 6-[2-anilino-1-(anilinocarbonyl)-2-oxoethyl]nicotinate (66 mg, TFA salt, 21%) as a white solid: ESIMS calcd 390.1 (M++H), found 390.1 (M++H).
