Reaction Steps

A mixture of 2,4-dichloro-5-methoxypyrimidine (0.68 g, 3.8 mmol), 3-cyclopentyl-3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl)propanenitrile (1.0 g, 3.17 mmol), tetrakis(triphenylphosphine)palladium (200 mg, 0.2 mmol), and potassium phosphate (2.0 g, 9.6 mmol) in 1,4-dioxane (9 mL) and water (0.9 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, concentrated. The residue was purified on silica gel, eluting with 0 to 60% EtOAc-hexanes, to give the desired product (860 mg, 82%). LCMS (M+H) 331.9.
