Reaction Steps

A suspension of 4-(3-chloro-pyrazin-2-yl)-6-methylsulfanyl-pyrimidine (37) (200 mg, 0.838 mmol), 2,6-dichloro-3,5-dimethoxyaniline (280 mg, 1.26 mmol), DPEphos (90 mg, 0.167 mmol), palladium (II) acetate (19 mg, 0.085 mmol) and cesium carbonate (546 mg, 1.68 mmol) in dioxane (8 mL) is degassed. After purging with Ar, the vial is sealed by the cap and irradiated at 150° C. for 30 minutes in Smith Synthesizer. The reaction mixture is evaporated and purified by silica gel flash chromatography eluting with ethyl acetate in hexanes from 10% to 30% to afford the desired product (2,6-dichloro-3,5-dimethoxy-phenyl)-[3-(6-methylsulfanyl-pyrimidin-4-yl)-pyrazin-2-yl]-amine (38).
