Procedure

A suspension of 0.5 g of the product of Step B, 50 ml of water, 15 ml of ethanol and 8 ml of 1 N sodium hydroxide solution was stirred overnight to obtain a clear colorless solution which was acidified with concentrated hydrochloric acid. The mixture was filtered to obtain 4-ethoxy-imidazo-[1,2-a]-quinoxaline-2-carboxylic acid melting at 220°-222° C.
