Reaction Steps

Palladium(II) acetate (9.3 mg, 0.041 mmol) and 2-(dicyclohexylphosphino)biphenyl (30 mg, 0.083 mmol) were stirred in dioxane (1.5 mL) for 15 minutes at room temperature under an atmosphere of nitrogen. Sodium tert.-butylate (76 mg, 0.78 mmol), 4-(2-methyl-oxazol-5-yl)phenylamine (90 mg, 0.52 mmol, CAS 89260-50-4) dissolved in dioxane (0.7 mL) and 4-benzyl-2-chloro-6-methyl-pyrimidine (124 mg, 0.57 mmol) were added. The reaction was heated 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 dichloromethane and then methylenechloride/methanol (19:1 v/v) as eluent to yield the title compound as a yellow solid (112 mg, 61%). MS ISP (m/e): 357.2 (100) [(M+H)+]. 1H NMR (CDCl3, 300 MHz): δ (ppm)=7.69 (d, 2H), 7.53 (d, 2H), 7.26-7.35 (m, 4H), 7.11-7.12 (m, 2H), 6.45 (s, 1H), 3.97 (s, 2H), 2.52 (s, 3H), 2.36 (s, 3H).
