A reaction mixture consisting of N-phenyl-4-chloro-1,2-dihydro-1-methyl-2-oxo-quinoline-3-carboxamide (12 parts), concentrated aqueous ammonia (25 parts), and methanol (60 parts) is heated in an autoclave at 100° C. for 48 hours. After cooling to room temperature the precipitate formed is filtered off and recrystallized from pyridine and dried to give N-phenyl-4-amino-1,2-dihydro-1-methyl-2-oxo-quinoline-3-carboxamide (1). M. p. 248° C.
