Reaction Steps
A mixture of 5-bromo-2-chloro-pyridine (Aldrich, Buchs, Switzerland, 392 mg, 2.04 mmol), 2-methyl-1H-imidazole (Aldrich, Buchs, Switzerland, 251 mg, 3.06 mmol) and cesium carbonate (1.33 g, 4.08 mmol) in DMA (10 ml) was heated by microwave irradiation for 20 min at 100° C. and 2.5 h at 150° C. The reaction mixture was quenched with diluted brine (200 ml) and cooled. The precipitate was filtered, washed with water and dried to give the title compound as off-white solid. (HPLC: tR 2.03 min (Method A); M+H=238, 240 MS-ES).
