Procedure

The compound (3.14 g, 4.30 mmol) obtained in Step 1 above was dissolved in dimethyl sulfoxide (40 ml) and methanol (40 ml), triethylamine (0.71 ml, 5.16 mmol) and a 1,1′-bis(diphenylphosphino)ferrocene-palladium (II) dichloride dichloromethane complex (351 mg, 0.43 mmol) were added and the resulting mixture was stirred under heating at 90° C. for 2 days under carbon monoxide atmosphere. Saturated sodium bicarbonate solution was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was washed with brine and then dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography [n-hexane:ethyl acetate=1:1 (v/v)] to give 0.40 g (13%) of the title compound as a yellow solid.
