Versuchsvorschrift

A suspension of Intermediate 1a (200 mg) obtained in Example 1-1, Step A, cyclopropylboronic acid (57 mg, Aldrich), anhydrous potassium phosphate (372 mg, Aldrich), and tricyclohexylphosphonium tetrafluoroborate (33 mg, Aldrich) in toluene (2 ml) was added with palladium acetate (10 mg, Wako Pure Chemical Industries), and the mixture was stirred at 80° C. with heating for 14 hours under a nitrogen gas atmosphere. The reaction mixture was cooled to room temperature, and then added with ethyl acetate (5 ml), and the insoluble solids were removed by filtration through Celite. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel chromatography (n-hexane:ethyl acetate=1:1) to obtain the title compound (53 mg).
