Procedure

First, 5.97 g of 4,6-dichloropyrimidine, 12.04 g of 3,5-dimethylphenylboronic acid, 8.48 g of sodium carbonate, 0.34 g of bis(triphenylphosphine)palladium(II) dichloride (Pd(PPh3)2Cl2), 20 mL of water, and 20 mL of 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)pyrimidinone (abbreviation: DMPU) were put into a recovery flask equipped with a reflux pipe, and the air in the flask was replaced with argon. This reaction container was subjected to irradiation with microwaves (2.45 GHz, 100 W) for 60 minutes to be heated. Here, into the flask were further put 2.58 g of 3,5-dimethylphenylboronic acid, 1.78 g of sodium carbonate, 0.070 g of Pd(PPh3)2Cl2, 5 mL of water, and 5 mL of DMPU, and irradiation with microwaves (2.45 GHz, 100 W) was performed again for 60 minutes so that heating was performed.
