Reaction Steps
A mixture of 1.2 g of (5Z,13E)-(9S,11R,15R,16RS)-9-hydroxy-16-fluoro-11,15-bis(tetrahydropyran-2-yloxy)-5,13-prostadienoic acid methyl ester (prepared from the corresponding acid in methylene chloride with 0.5-molar diazomethane solution at 0° C.), 800 mg of p-toluenesulfonic acid chloride, and 4 ml of pyridine is agitated for 16 hours at 0° C., then for 48 hours at 25° C. The mixture is worked up according to Example 1. Yield: 1.45 g of the 9-tosylate as an oil.
