Reaction Steps

To a solution of 6,7-bis(palmitoyloxy)-4-thiaheptanoic acid as obtained in Reference Example 4 (200 mg) and glycine t-butyl ester hydrochloride (60 mg) in dimethylformamide (3 ml), triethylamine (0.099 ml) and diethyl cyanophosphate (72 ml) were added, followed by stirring at room temperature for 17 hours. After addition of water, the reaction mixture was extracted with chloroform. The extract was washed with a 5% aqueous solution of citric acid, a saturated aqueous solution of sodium. hydrogen carbonate and saturated saline, and dried over anhydrous sodium sulfate, and the solvent was distilled off. The resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=1:3) to yield the title compound (206 mg, yield 90%) as a wax-like substance.
