PROCEDURE

实验过程

To a solution of 6,7-bis(12-phenyldodecanoyloxy)-4-thiaheptanoic acid as obtained in Reference Example 34 (200 mg) and 4-aminobenzoyl-glutamic acid di-t-butyl ester (108 mg) in pyridine (6 ml), phosphorus trichloride (4 drops) was added drop by drop, followed by stirring at room temperature for 1 hour. After the solvent was concentrated, the residue was purified by silica gel column (n-hexane:ethyl acetate=2:1) to yield the title compound (282 mg, yield 93%) as a colorless oily substance.
