Reaction Steps

In 250 mL round bottom flask were charged benzo[d]thiazol-2-yl(4-hydroxyphenyl)methanone (6.0 g, 23.5 mmol), 2,3-dichloro-pyrazine (3.48 g, 23.5 mmol), DMSO (60 mL), and cesium carbonate (15 g, 47 mmol). The reaction mixture was stirred at 90° C. for 6 h. The reaction mixture was diluted with cold water and the precipitate was collected by filtration. The crude product was purified by silica gel column chromatography with hexane and ethyl acetate to give the title compound. [M+H]=368.
