Procedure

To a solution of 4-[2-[2-(4-chlorophenyl)sulfonylamino-5-chlorophenyl]vinyl]benzoic acid (54 mg; prepared in Example 5.) in THF (4 ml), platinum oxide hydrate (3 mg) was added. The mixture was stirred for 2 hours at room temperature in a stream of hydrogen. The reaction mixture was filtered and the filtrate was concentrated under the reduced pressure. To the residue, methylene chloride was added. The mixture was stirred. The precipitate was collected by filter to give the title compound (46 mg) having the following physical data.
