Sodium Chloride → Cyclopentyl 3-cyclopentyloxy-4-(methylthio)benzoate

Participants

Reaction Steps

Sodium thiomethoxide (0.177 g, 2.5 mmol) is added portionwise to a stirred solution of cyclopentyl 3-cyclopentyloxy-4-nitrobenzoate (0.64 g, 2 mmol) in N,N'-dimethylimidazolidinone (10 mL) at ambient temperature under an atmosphere of nitrogen and stirring continued for 4 hours. The mixture is then diluted with water (100 mL) containing sodium chloride (15 g) and extracted with ethyl acetate (2×50 mL). The combined extract is washed with saturated brine (1×100 mL) and then dried over magnesium sulfate and evaporated under reduced pressure to give cyclopentyl 3-cyclopentyloxy-4-(methylthio)benzoate (0.52 g, 81%) as a brown viscous oil which is used without further purification.
