Participants

Reaction Steps

To a solution of 500 mg of 5,6-diphenyl-2-pyrazinethiol in 20 ml of acetone, 321 mg of sodium carbonate was added and a solution of 556 mg of 2-(4-bromobutyloxy)acetic acid tert-butyl ester in 2 ml of acetone was added dropwise while stirring under ice-cooling, followed by stirring at room temperature for 24 hours. The solvent was evaporated under reduced pressure, and then the residue was combined with water and extracted with ethyl acetate. The extract was washed with saturated brine and dried over anhydrous magnesium sulfate, and then the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to obtain 701 mg of the desired compound as a pale yellow oily substance.
