A solution of 4-[6,7-bis(octadecylcarbamoyloxy)-4-thiaheptanoylamino]benzoyl-glutamic acid di-t-butyl ester as obtained in Example 31 (100 mg) in trifiuoroacetic acid (2 ml)-dichloromethane (0.5 ml) was stirred at room temperature for 1 hour. After solvent concentration under reduced pressure, the resulting residue was crystallized from chloroform-methanolwater to yield the title compound (99 mg, yield 100%) as a colorless powder.
