Procedure

4 ml of a methanolic solution containing 165 mg (0.255 mmol) of 1-{4-t-butyl-3-[2-(9H-xanthen-9-yl)acetamido]phenyl}-6-phenylhexyl hydrogen succinate (prepared as described in Example 54) were cooled in an ice bath, and then 2.42 ml (0.242 mmol) of a 0.1N aqueous solution of sodium hydroxide was added dropwise. The reaction solution was condensed by evaporation under reduced pressure, whilst keeping its temperature below 15° C. 20 ml of toluene were added to the residue, and then sufficient ethanol was added until the solution became homogenous. The solvent was then was removed by distillation under reduced pressure. In order to remove any remaining water, toluene was added to the residue and the mixture was distilled again. This procedure was repeated several times, and gave 170 mg (a quantitative yield) of the title compound as a foam-like substance.
