Procedure

In 30 ml of acetone, 5.28 g (0.01 mol) of 2-(3-dodecoxypropylcarbamoyl)-5-isobutoxycarbonylamino-1-naphthol synthesized in accordance with the method described in JP-A No. 123158/1987 was dissolved and 2.00 g (0.01 mol) of 1,3-dichloro-5,5-dimethylhydantoin was added to the solution, followed by stirring for 2 hours at room temperature. Then 50 ml of ethyl acetate was added to the reaction mixture, followed by washing with a 5% aqueous sodium hydroxide solution and then washing with water. The solvent was distilled off and crystallization from acetonitrile was carried out, to give 5.17 g (yield: 92%) of 2-(3-dodecoxypropylcarbamoyl)-4-chloro-5-isobutoxycarbonylamino-1-naphthol
