Reaction Steps

A mixture of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.1 g, 0.5 mmol), cyclopentylmethyl methanesulfonate (0.10 g, 0.58 mmol), and sodium hydride (31 mg, 0.77 mmol) in N,N-dimethylformamide (1 mL) was stirred at 110° C. for 2 h. After cooling it was diluted with ethyl acetate, washed with water twice, brine once; dried over Na2SO4. After filtration the filtrate was concentrated to yield 0.11 g of the product which was directly used in the next step reaction without further purification.
