Reaction Steps

0.515 g (3 mmol) of copper(II) acetate and 0.306 ml (4 mmol) of pyridine were added to 0.5 g (2 mmol) of methyl[5-(4-chlorophenyl)-3-methyl-1H-pyrazol-4-yl]acetate in 10 ml of dichloromethane. 0.598 g (4 mmol) of 2-chloropyrimidine-5-boronic acid was then added, and the mixture was stirred at 20° C. for 24 h. The mixture was then added to 1 M HCl and extracted with dichloromethane. The combined organic phases were dried with magnesium sulfate, filtered and concentrated. The crude product was purified by preparative HPLC. This gave 0.015 g of product (2% of theory).
