Reaction Steps

Add diethyl ethoxymethylenemalonate (10.0 ml, 55.0 mmol) to a solution of 6-methyl-pyridin-2-ylamine (5.41 g, 50.0 mmol) in toluene (100 ml). Heat the mixture under reflux overnight. Evaporate the solvent in vacuo to provide 2-[(6-methyl-pyridin-2-ylamino)-methylene]-malonic acid diethyl ester (14.8 g) as a white solid. MS (ES+): 279 (M+H).
