PROCEDURE

实验过程

Under an atmosphere of argon, a mixture of 4-(4-bromo-2-methoxyphenyl)-1-(3-(trifluoromethyl)phenyl)-3,4,7,8-tetrahydroquinazoline-2,5(1H,6H)-dione (intermediate 50, 21 mg, 42 μmol), copper(I) cyanide (10 mg, 0.11 mmol) and tetrakis(triphenylphosphine)-palladium(O) (5 mg, 4 μmol) in N,N-dimethylformamide (1 mL) is heated at 140° C. over it) night. The mixture is cooled at room temperature, diluted with methanol and purified by reversed phase HPLC (Waters SunFire™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 4 mg; ESI mass spectrum [M+H]+=442; Retention time HPLC: 0.87 min (Z011_S03).
