実験手順
Into a solution of (-)-4-[N-(3-methoxypropyl)-N-pentylcarbamoyl]-5-(2-naphthylsulfonyl)pentanoic acid (4.00 g) in ethanol (40 ml) was added dropwise a 1N sodium hydroxide solution (8.39 ml) with stirring at 0° C. The reaction mixture was concentrated in vacuo at 35° C., and water-ethanol (1:1, 40 ml) was added and concentrated again in vacuo to the residue. The residue was recrystallized from isopropyl ether (40 ml) to give 3.90 g of sodium (-)-4-[N-(3-methoxypropyl)-N-pentylcarbamoyl]-5-(2-naphthylsulfonyl)pentanoate as a hygroscopic amorphous solid.
