Pyridine → Tetrahydrofuran-3-yl 4-methylbenzenesulfonate

Participants

Reaction Steps

A stirred solution of 10.0 g (0.11 mole) of 3-hydroxytetrahydrofuran in 36.0 g (0.46 mole) of pyridine was cooled in an ice bath and 22.0 g (0.12 mole) of 4-methylphenylsulfonyl chloride was added. Upon complete addition, the reaction mixture was stirred at ambient temperature for 60 hours. The reaction mixture was poured into ice-water, and the mixture extracted with diethyl ether. The combined ether extracts were washed several times with water. The organic layer was dried with magnesium sulfate, filtered, and the filtrate concentrated under reduced pressure to give 21.4 g of 3-tetrahydrofuranyl 4-methylphenylsulfonate.
