Reaction Steps

1.0 g (2.93 mmol) of methyl 3-bromomethyl-2-chloro-4-methylsulfonylbenzoate was dissolved in 10 ml of cyclohexanol and treated with 0.33 g (2.93 mmol) of potasisum tert-butoxide. The mixture was stirred overnight at room temperature and then concentrated on a rotary evaporator. The residue was dissolved in 16 ml of tetrahydrofuran and 8 ml of water and refluxed for 4 h together with 0.55 g of NaOH (13.74 mmol). It was then allowed to cool and was largely concentrated on a rotary evaporator and the aqueous residue was then treated with 2 M HCl. It was then extracted with methylene chloride, and the combined organic phase was dried over MgSO4 and completely concentrated on a rotary evaporator.
