Reaction Steps

To a solution of 2-amino-4-cyanopyridine (4.00 g, 33.6 mmol) in THF (100 mL) add ethyl bromopyruvate (6.55 g, 33.6 mmol). Stir the mixture at rt overnight. A light yellow suspension forms. After filtration and washing with THF, dissolve the light yellow solid in EtOH (50 mL) and heat to reflux for 4 h. Concentrate in vacuo to afford the desired product 7-cyano-imidazo[1,2-a]pyridine-2-carboxylic acid ethyl ester as a solid (6.21 g, 28.9 mmol).
