Reaction Steps

A mixture of 2-chloro-6-((cyclopropylmethoxy)methyl)-N-methylpyrimidin-4-amine (41 mg, 0.18 mmol), 3-methoxy-4-(4-methyl-1H-imidazol-1-yl)aniline (73 mg, 0.36 mmol), cesium carbonate (117 mg, 0.36 mmol), palladium acetate (6 mg, 0.03 mmol) and 2-(dicyclohexyl-phosphino)biphenyl (9 mg, 0.03 mmol) was stirred under argon at 120° C. for 90 minutes in microwave oven. The mixture was filtered through a short silica gel plug which was washed with 10% solution of methanol in ethyl acetate (75 mL). The eluate was concentrated and the residue was purified by preparative HPLC to give the title compound as a dry film (30 mg, 42%).
