Reaction Steps

Palladium(II) acetate (5.9 mg, 0.026 mmol) and 2-(dicyclohexylphosphino)biphenyl (19 mg, 0.052 mmol) were dissolved under an atmosphere of nitrogen in dioxane (2 mL). The reaction was stirred for 25 minutes at room temperature. Sodium tert.-butylate (48 mg, 0.49 mmol), 3-methoxy-4-(3-methyl-[1,2,4]triazol-1-yl)-phenylamine (67 mg, 0.33 mmol) dissolved in dioxane (1.5 mL) and 4-benzyl-2-chloro-6-methyl-pyrimidine (79 mg, 0.36 mmol) were added. The reaction was heated three times for 30 minutes to 200° C. in a microwave oven. Water was added and the reaction was extracted twice with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered and the solvent was evaporated under reduced pressure. The residue was purified by column chromatography on silica gel using methylenechloride/methanol (19:1 v/v) as eluent to yield the title compound as a yellow gum (38 mg, 30%). MS ISP (m/e): 387.3 (100) [(M+H)+]. 1H NMR (CDCl3, 300 MHz): δ (ppm)=8.49 (s, 1H), 7.97 (s, 1H), 7.56 (d, 1H), 7.26-7.33 (m, 5H), 6.98 (d, 1H), 6.51 (s, 1H), 3.97 (s, 2H), 3.83 (s, 3H), 2.48 (s, 3H), 2.37 (s, 3H).
