Procedure

To a solution of tert-butyl({6-[(4-bromobenzyl)(pyridin-3-ylsulfonyl)aminomethyl]pyridin-2-yl}tert-butoxycarbonylamino)acetate (185 mg, 0.285 mmol) obtained in Example 9-(a) in toluene (2 ml) were added 4-fluorophenylboronic acid (61.3 mg, 0.438 mmol), palladium acetate (4.9 mg, 0.044 mmol), tripotassium phosphate (202 mg, 0.953 mmol) and water (0.2 ml), followed by being subjected to argon atmosphere. Then a 20% solution of tricyclohexylphosphine in toluene (130 μl, 0.088 mmol) was added to the mixture, and it was stirred at 100° C. for 2.5 hours under argon atmosphere. After completion of the reaction, a saturated aqueous sodium chloride solution was added to the reaction solution, followed by extraction with ethyl acetate. The separated organic layer was dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography (eluent; hexane:ethyl acetate=9:1→7:3 (V/V)), and fractions containing the desired compound were concentrated under reduced pressure to afford the title compound (178 mg) as a white foam. (Yield: 94%)
