Procedure

Compound 187a (0.93 g) obtained in Step A, ethyl 4-iodobenzoate (0.34 ml), palladium acetate (0.05 g), and sodium carbonate (0.54 g) were dissolved in DMF (10 ml), followed by stirring for 6 hours at 60° C. The reaction solution was mixed with an aqueous ammonium fluoride solution and diethyl ether, and then, filtered with Celite. The organic layer was extracted from the resultant, washed with a saturated aqueous sodium chloride solution, dried over magnesium sulfate anhydride, and evaporated under reduced pressure for removing the solvent. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=4/1) to give Compound 187 (0.30 g, 50%) as colorless crystals.
