Procedure
To 2 ml of N,N-dimethylformamide deaerated with argon for 10 minutes, 213 mg (1.10 mmol) of 5-bromo-2-chloropyrimidine, 181 mg (1.05 mmol) of 3-(methoxycarbonyl)phenylboronic acid, 315 mg (2.97 mmol) of sodium carbonate and 22.4 mg (0.100 mmol) of palladium acetate were added, and the mixture was stirred at 110° C. for 3 hours. After completion of the reaction, the reaction solution was poured into water and extracted with toluene three times. The obtained organic phases were combined, washed with saturated sodium chloride aqueous solution, dried with magnesium sulfate and then filtered, and the solvent was distilled off under reduced pressure. The obtained residue was subjected to silica gel column chromatography [n-hexane/ethyl acetate=92/8-76/24 (V/V)] and the fraction including the desired compound was concentrated under reduced pressure to provide 74 mg of the title compound as a white solid (yield: 28%).
