The reaction solution was heated to reflux for 2 hours and it was terminated by adding saturated aqueous solution of ammonium chloride. A great amount of precipitate was produced which was filtered. The organic phase was collected, dried, evaporated, and the resulting residue purified with a silica gel column (n-hexane: ethyl acetate = 10: 1) to give 400 mg of colorless liquid 5A.
