Procedure

A mixture of 92.5 g (0.37 mol) of 6-(3-acetylaminophenyl)-1,2-dihydro-2-oxonicotinonitrile, 185 g of potassium hydroxide, and 740 ml of water is heated at 105° for 30 hrs. The cooled reaction mixture is poured into 285 ml of concentrated hydrochloric acid and ice. The pH of the suspension is adjusted to 5.0 with aqueous sodium hydroxide solution and the solid filtered, washed with water, and dried to give 81.2 g of 6-(3-aminophenyl)-1,2-dihydro-2-oxonicotinic acid. ##EQU49##
