Azobisisobutyronitrile → Dimethyl 4-[2-(acetylthio)ethyl]-1,3-benzenedicarboxylate

Participants

Reaction Steps

To a degassed solution of dimethyl 4-ethenyl-1,3-benzenedicarboxylate (415 mg, 1.88 mmol) in benzene (6 mL) were added AIBN (33 mg, 0.21 mmol) and thioacetic acid (0.27 mL, 3.78 mmol), and the mixture was refluxed for 5 hours. The reaction mixture was diluted with aqueous NaHCO3 solution (15 mL) and extracted with EtOAc (15 mL). The organic layer was dried over MgSO4 and concentrated. The residual material was purified by silica gel chromatography (hexanes/EtOAc=10:1) to give 0.150 g of colorless oil (27% yield).
