2,3-Dichloro-5,6-dicyano-1,4-benzoquinone → HCID 66597208, compound

Participants

Reaction Steps

A suspension of methyl [2-methyl-4-p-tolyl-5,6,7,8-tetrahydro[1]benzothieno [2,3-b]pyridin-3-yl]acetate (0.225 mg; 0.616 mmol) and 2,3-Dichloro-5,6-Dicyanobenzoquinone (0.351 mg; 1.546 mmol) in 1,2-dichlorobenzene (2 mL) was placed in a sealed tube and was irradiated in a microwave oven at 190° C. for 10 minutes. The reaction mixture was then evaporated to dryness under reduced pressure. The residue was suspended in dichloromethane and the solid was filtered through celite. The filtrate was concentrated under reduced pressure and the residue was purified by flash chromatography on silica gel using a gradient of ethyl acetate (10-30%) in heptane to afford 0.125 g (56%) of the title compound as a pink solid.
