Participants

Reaction Steps

3-Butyryl-8-ethoxy-4-methanesulfonyloxy-1,7-naphthyridine (338 mg) and o-toluidine (214 mg) were dissolved into 7 ml of acetonitrile, and the solution was heated to reflux for 30 minutes and concentrated to evaporate solvent under reduced pressure. Water was added to the residue, and the mixture was extracted with chloroform, and the organic phase was washed with water and then saturated sodium bicarbonate. After dying, and concentration under reduced pressure, the resulting residue was subjected to silica gel column chromatography using a mixture of hexane:ethyl acetate (2:1) as an eluant to give yellow titled compound (300 mg, 86%)
