実験手順

Palladium (II) acetate (3.6 mg, 0.016 mmol) and 2-(dicyclohexylphosphino)biphenyl (11.6 mg, 0.032 mmol) were stirred under nitrogen at room temperature in dioxane (1.8 mL) for 10 minutes. Sodium tert.-butylat (29 mg, 0.3 mmol), (4-phenyl-4,5,6,7-tetrahydro-benzothiazol-2-yl)-piperidin-4-yl-amine dihydrochloride (77.3 mg, 0.2 mmol), N,N-diisopropylethylamine (69 L, 0.4 mmol) and 5-chloro-3-methyl-[1,2,4]thiadiazole (29.6 mg; 0.22 mmol) were added and the reaction was heated to 200° C. for 30 minutes in a microwave oven. The reaction was diluted with water and extracted twice with ethyl acetate. The combined organic layers were washed with water, dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel using heptane/EtOAc 4:1 to 1:4 (v/v) as eluent. The title compound was obtained as a white solid (55 mg, 67%).
