Procedure

A solution of 5.9 g of 4-(diethylphosphonomethyl)-2-cyanoquinoline in 24 ml of concentrated sulfuric acid is heated at 80° for 5 minutes, cooled to 0° and added slowly to an ice-cooled mixture of 50 g of sodium carbonate in 50 ml of water and 100 ml of methylene chloride. The organic layer is separated, dried over sodium sulfate and evaporated to dryness to yield 4-(diethylphosphonomethyl)-quinoline-2-carboxamide.
