The mixture was stirred at 23° C. for one hour. It was then filtered and washed with ether to give 8.7 gram of solid. This solid was then dissolved in 50 ml ethanol and refluxed for two hours. The reaction mixture was cooled to room temperature and partitioned between 350 ml chloroform and 200 ml saturated sodium bicarbonate. The organic layer was separated and dried over magnesium sulfate. Filter off the drying agent and concentrate to give 6.5 gram of product.
