Procedure

To a solution of 2,6,7-trichloro-3-isopropylquinoxaline (69 mg, 0.25 mmol) in DMF (4 ml) was added potassium fluoride 40% wt on alumina (109 mg, 0.75 mmol) followed by addition of 2-mercapto-5-methylsulfanyl-1,3,4-thiadiazole (44 mg, 0.26 mmol). The reaction was stirred overnight at room temperature. The product was purified by flash column chromatography using ethyl acetate:hexanes 1:20 to afford the title compound.
