Procedure

3-Methyl-4-phenyl-6-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-3,4-dihydro-1H-quinazolin-2-one (457 mg, 1.255 mmol), 4-Iodo-3-methoxy-5-methyl-isoxazole (150 mg, 0.628 mmol), potassium carbonate (173 mg, 1.255 mmol) and Pd(dppf)Cl2 (102.5 mg, 0.126 mmol) are added to a microwave vessel. Dimethoxyethane (0.1 mL) and water (0.1 mL) are added and the vessel flushed with argon. The mixture is heated in a microwave reactor at 120° C. for 3.5 hours. The reaction mixture is extracted with ethyl acetate from water. The organic phase is dried over Na2SO4 and the solvent is removed on a rotary evaporator. The residue is purified by reversed phase HPLC.
