Reaction Steps

Palladium(II) acetate (3.6 mg, 0.016 mmol) and 2-(dicyclohexylphosphino)biphenyl (11 mg, 0.032 mmol) were stirred in dioxane (1 mL) for 10 minutes at room temperature under an atmosphere of nitrogen. Sodium tert.-butylate (29 mg, 0.3 mmol), 4-(3-methyl-[1,2,4]-thiadiazol-5-yl)-phenylamine (38 mg, 0.20 mmol) and) 2-[2-chloro-6-(4-trifluoromethyl-phenyl)pyrimidine-4-yl]-propan-2-ol (70 mg, 0.22 mmol) dissolved in dioxane (1 mL) were added. The reaction was heated for 30 minutes to 130° C. in a microwave oven. Water was added and the reaction was extracted twice with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate, filtered and the solvent was evaporated under reduced pressure. The residue was purified by column chromatography on silica gel using heptane/ethyl acetate (1:1 v/v) as eluent to yield the title compound as a yellow solid (26 mg, 28%). MS ISP (m/e): 472.2 (100) [(M+H)+]. 1H NMR (CDCl3, 300 MHz): δ (ppm)=8.21 (d, 2H), 7.97 (d, 2H), 7.85 (d, 2H), 7.79 (d, 2H), 7.45 (br s, 1H, NH), 7.39 (s, 1H), 3.72 (s, 1H, OH), 2.73 (s, 3H), 1.62 (s, 6H).
