Procedure

To a solution of the compound prepared in Example 2(6) (215 mg) in diphenyl ether (3 ml), 10% palladium carbon (150 mg) was added, and the mixture was stirred for 4 hours at 250° C. After the reaction mixture was cooled to room temperature, it was diluted with methanol (10 ml). The diluted solution was filtered though celite (registered trademark). The filtrate was concentrated, and the residue was purified by column chromatography on silica gel (n-hexane:acetone=9:1) to give the title compound (150 mg) having the following physical data.
