Reaction Steps
4,6-Dichloropyrimidine (5.58 g, 37.4 mmol) and 3-nitrophenylboronic acid (5.00 g, 27.2 mmol) were added to a stirred mixture of dimethoxyethane (112 mL) and water (17 mL), followed by the addition of NaHCO3 (6.28 g, 75 mmol) and (PPh3)2PdCl2 (0.787 g, 1.12 mmol) herein, and the reaction mixture was refluxed for 8 h. The solvent was removed under reduced pressure. The residue was taken up in CH2Cl2 (100 mL), and the resulting solution washed with water, dried over anhydrous K2CO3, filtered and the solvent removed under reduced pressure. The crude product was purified by column chropatography on silica (eluent CH2Cl2) to yield 4-chloro-6-(3-nitro-phenyl)-pyrimidine (5.52 g; 86%) as yellowish solid.
