Procedure
A mixture of 0.37 g of 4-hydroxy-3-[3-[3-[(methoxycarbonylmethyl)aminocarbonyl]phenyl]-1-oxo-2-propenyl]-6-methyl-2(1H)-pyridinone, 18 mg of ammonium chloride and 4 ml of aqueous concentrated ammonia was stirred at room temperature for 1 hour. Two ml of aqueous concentrated ammonia was added, and this was further stirred for 30 minutes, and concentrated under reduced pressure. The residue was washed with tetrahydrofuran, and the resulting crude crystals were recrystallized from dimethylformamide to obtain 0.11 g of 4-hydroxy-3-[3-[3-[(aminocarbonylmethyl)aminocarbonyl]phenyl]-1-oxo-2-propenyl]-6-methyl-2(1H)-pyridinone [Compound No. (91a)] as a yellow crystal.
