実験手順

4-chloro-2-morpholin-4-yl-1,3-thiazole-5-carbonitrile (0.200 g, 0.871 mmol), 2,4-dichlorophenylboronic acid (0.249 g, 1.31 mmol), bis(triphenylphosphine)palladium dichloride (0.061 g, 0.0871 mmol), sodium carbonate (0.184 g, 1.74 mmol) were taken up in DME (3 mL), ethanol (1 mL) and water (1 mL) and microwaved at 125° for 30 minutes. Mixture was diluted with ethyl acetate (10 mL) and extracted. The organic phase was dried with sodium sulfate, filtered and evaporated. ISCO purification on silica gel using 10% ethyl acetate in hexane to 50% ethyl acetate in hexane afforded the title compound (45 mg, 15%). LCMS: (FA) ES+, 340. 1H NMR (400 MHz, d6-DMSO) δ: 7.44 (d, 1H), 7.20-7.17 (m, 2H), 3.43-3.28 (m, 4H), 3.16-2.93 (m, 4H).
