Reaction Steps

One part of dicyclohexyl 2-benzylsulfonyl-3,6-dihydroxyterephthalate, 2 parts of electrolytic manganese dioxide and 3 parts of toluene were agitated at 35°-45° C. for 8 hours and then at its boiling point for additional 2 hours. The reaction mixture was hotfiltered and the volume of the resultant filtrate was concentrated to about 1/3. After adding ligroin to the concentrate, the resultant mixture was allowed to cool to obtain light-yellowish crystals with a yield of 60%. Upon recrystallization, they showed a melting point of 160°-162° C. Detailed analysis data of this compound, such as its elementary analysis data, are as described before.
