実験手順

3-(3,4-Dimethoxy-phenyl)-1H-pyrrolo-[2,3-b]pyridine 1 (40 mg, 0.16 mmol) was dissolved in benzene and 4-chlorophenyl isocyanate (36 mg, 0.24 mol) dissolved in tetrahydrofuran (4 mL) was added. 4-Dimethylaminopyridine (20 mg, polymer bound) was added. The reaction was heated in a CEM Discover microwave at 200° C. for 10 minutes. The mixture was filtered and concentrated. The resulting solid was washed with a minimum of methanol, filtered, and then washed with dichloromethane to provide 26, (26 mg, 40%). MS(ESI) [M+H+]+=408.4.
