Reaction Steps

A mixture of 5-bromo-2-(4-methyl-imidazol-1-yl)-benzonitrile (200 mg, 0.76 mmol), 2-amino-4,6-dimethyl-pyrimidine (141 mg, 1.14 mmol), sodium phenoxide (266 mg, 2.29 mmol), tris(dibenzylideneacetone)dipalladium chloroform complex (21 mg, 0.02 mmol) and 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene=xanthphos (26 mg, 0.04 mmol) in 5 mL of dioxane was heated to 80° C. under argon for 2 hours. The mixture was diluted with water, extracted with ethyl acetate and the product purified by by chromatography on silica gel using dichloromethane/methanol 9:1 v/v as an eluent. The title compound was obtained as a colorless solid (144 mg, 62%). MS ISP (m/e): 305.1 (100) [(M+H)+]. 1H NMR (DMSO-D6, 300 MHz): 8 (ppm)=10.08 (s, 1H), 8.44 (s, 1H), 8.15 (d, 1H), 7.89 (s, 1H), 7.55 (d, 1H), 7.25 (s, 1H), 6.76 (s, 1H), 2.36 (s, 6H), 2.18 (s, 3H).
