5.2 g of bis(choline)-naphthalene-1,5-disulfonate was suspended in 30 ml of acetonitrile, and 10 g of lactic acid anhydride diacetate was added thereto. This mixture was refluxed for 3 hours. The resulting reaction mixture was allowed to stand at room temperature while cooling to precipitate the desired product crystals, which were collected by filtration. 5.5 g (76% yield) of the desired product having a melting point of 189°C to 191°C were obtained.
