反応手順
A mixture of 2,4,6-trichloropyrimidine 8 (1 g, 5.45 mmol), phenylboronic acid (665 mg, 5.45 mmol), Pd(PPh3)4 (100 mg) and 2N aqueous Na2CO3 (4.1 mL) in 1:1 toluene:EtOH (15 mL) was heated in a microwave at 120° C. for 20 min. The reaction mixture was diluted with EtOAc and washed with H2O and brine. The organic layer was dried over MgSO4 and concentrated in vacuo to give 2,4-dichloro-6-phenylpyrimidine as a solid (1.35 g), which was used without further purification in the next step.
