反応手順
According to Scheme 13 Step 1: A suspension of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (7.38 mmol, 1.43 g), 1-(chloromethyl)-4-methoxybenzene (7.38 mmol, 1.00 mL) and K2CO3 (7.38 mmol, 1.02 g) in acetonitrile (10 mL) was heated at 80° C. for 5 hours. Water was added and the aqueous phase was extracted with DCM. The organic phase was dried over Na2SO4, was filtered and was concentrated under reduced pressure to afford 1-(4-methoxybenzyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (6.68 mmol, 2.10 g, 91%) as a yellow oil.
