Reaction Steps
A mixture of 8-acetyl-12-hydroxy-13-(4-fluorophenoxy)tridecanoic acid (9.5 g., 0.025 mole) and acetic anhydride (6.1 g., 0.06 mole) is heated at 60° for 18 hours. The mixture is then cooled and dissolved in 80 ml. of ether. The solution is extracted with an ice-cold solution of 8 g. of sodium hydroxide in 150 ml. of water. The basic solution is separated and acidified with concentrated hydrochloric acid. The oily acid that separates is taken up in ether, washed with water and dried over sodium sulfate. The ether is evaporated to leave the crude product as a viscous yellow oil.
