A mixture of compound benzo[1,3]dioxo-5-yl boronic acid (0.14 g, 83 mmol), and compound 1-(4-chloro-6-phenyl-pyrimidin-2-yl)-piperidin-4-ol (90.2 g, 69 mmol), (PPh3)4Pd (31 mg, 0.03 mmol) and sodium carbonate (0.73 g, 69 mmol) in dimethylformamide (5 mL) was stirred for 1 hour at 25° C. and then for 12 hours at 80° C. under nitrogen atmosphere. The mixture was cooled to temperature in the range of 20-40° C., diluted with water (10 mL) and extracted with ethyl acetate (3×10 mL). The organic layers were collected, combined, washed with water (10 mL), dried over anhydrous sodium sulphate, and concentrated under vacuum. The residue thus obtained was purified by column chromatography using ethyl acetate-petroleum ether to give the desired compound.
