The product from Example 2 is used as a stating material in this procedure. The resulting product from Example 2 was diluted in 200 mL of toluene. Next, 0.125 g of toluensulfonic acid was added to the reaction mixture. The reaction mixture was refluxed under argon atmosphere for 44 hours. The mixture was then washed with 50 mL of water and the solvent was removed under vacuum. The resulting product was then purified by silica gel chromatography with the use of 90% hexane and 10% ethyl acetate. The resulting product was recovered as the solvent was removed under vacuum.
