Reaktionsschritte
A mixture of 2,4-dichloro-5-methoxypyrimidine (from Aldrich Chemicals, 1.47 g, 0.00821 mol), 3-cyclopropyl-3-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl]propanenitrile (from example 177 step 1, 2.34 g, 0.00815 mol), tetrakis(triphenylphosphine)palladium(0) (0.6 g, 0.0005 mol), and potassium phosphate (5.2 g, 0.025 mol) in 1,4-dioxane (20 mL, 0.3 mol) and water (2 mL, 0.1 mol) was heated at 100° C. overnight. After cooling to room temperature, the mixture was dilute with AcOEt, washed with water, brine, dried over MgSO4, concentrated. The residue was purified on silica gel, eluting with 0 to 60%, to give the desired product (580 mg, 23.43%). LCMS (M+H) 304.3
