실험 절차

A mixture of 2,4-dichloropyrimidine (2.8 g, 0.019 mol), 3-cyclopropyl-3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl)propanenitrile (4.50 g, 0.0157 mol), tetrakis(triphenylphosphine)palladium (1.0 g, 0.9 mmol), and potassium phosphate (0.1 g, 0.047 mol) in 1,4-dioxane (50 mL) and water (5 mL) was heated at 100° C. overnight. After cooling to room temperature, the mixture was diluted with EtOAc, washed with water, brine, dried over MgSO4, and concentrated. The residue was purified on silica gel, eluting with 0 to 100% EtOAc in hexanes, to give the desired product as racemic mixture (3.08 g, 71.81%). LCMS (M+H) 274.3.
