Reaction Steps

To a solution of 2.3 g of sodium and 200 ml of ethanol was added 5.1 g of 2-amino-N-(1H-tetrazol-5-yl)benzamide and 11.0 g of diethyl oxalate. The resulting solution was heated at 50° C. for 20 hours and then acidified with glacial acetic acid. The clear acid solution obtained was diluted with water and the solid which formed was separated by filtration, washed with water and air-dried to give 2-oxo-N-[2-((1H-tetrazol-5-yl)aminocarbonyl)phenyl]glycine ethyl ester melting at about 231°-232° C.
