실험 절차

Under a nitrogen atmosphere, into a reaction vessel were charged 10.49 g (content: 86%, net quantity: 9.02 g (47.3 mmol)) of (2Z)-4-[(4-aminophenyl)amino]-4-oxo-2-butenoic acid and 30 ml of water. To this was added 47.3 ml (47.3 mmol) of a 1 mol/L sodium hydroxide aqueous solution. After completion of the reaction, the solution was condensed to dryness to obtain a solid to which 30 ml of tetrahydrofuran was added, and the mixture was stirred at room temperature for 30 minutes, then, the deposited crystal was isolated by filtration, and dried to obtain 11.28 g of sodium (2Z)-4-[(4-aminophenyl)amino]-4-oxo-2-butenoate di-hydrate as a yellow solid. Yield: 90%
