Reaction Steps

To a solution of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (1.25 g, 0.00644 mol) in acetonitrile (20 mL, 0.4 mol) was added (2E)-3-(tetrahydro-2H-pyran-4-yl)acrylonitrile (1.00 g, 0.00729 mol), followed by 1,8-diazabicyclo[5.4.0]undec-7-ene (1.09 mL, 0.00729 mol). The resulting mixture was stirred at room temperature overnight. After being evaporated to dryness, the residue was purified on silica gel, eluting with 0-100% EtOAc in hexanes, to provide the desired product (1.30 g, 60.93%). LCMS (M+H) 332.4.
