Participants

Reaction Steps

A solution of 3-(1-benzenesulphonylcyclopent-3-enyl)propan-1-ol (56 mg, 0.21 mmol) and triethylamine (41 μL, 0.29 mmol) in dichloromethane (5 ml) was cooled to 0° C. and treated with methanesulphonyl chloride (21 μL, 0.27 mmol). The mixture was allowed to warm to room temperature and stirred for 30 minutes, then diluted with water and extracted with ethyl acetate. The combined organic layers were dried (MgSO4) and concentrated in vacuo. The residue was dissolved in acetonitrile (5 ml), treated with 3,4-dimethyl-1,2,5,6-tetrahydropyridine (397 mg, 0.32 mmol) and potassium carbonate (58 mg, 0.42 mmol) and heated at 60° C. for 3 hours. The mixture was diluted with water and extracted with ethyl acetate. The combined organic layers were dried (MgSO4) and concentrated in vacuo. The residue was purified by preparative thin layer chromatography, eluting with 5% methanol/dichloromethane, to give the title compound.
