Reaction Steps
A solution of 25 g 3-cyano-1-ethyl-1,4-dihydro-4-oxocinnoline, 100 g sodium hydroxide, 400 ml ethanol and 100 ml water was stirred at 70° C. for 3 hr. After the removal of ethanol by evaporation, to the mixture was added conc. hydrochloric acid to precipitate crystalline materials. Precipitates were separated by filtration, washed with water, ethyl ether/ethanol and dried to yield 25.6 g of the desired compound. Mp.=206°-208° C.
