Tetrahydrofuran → HCID 85906473, compound

Participants

Reaction Steps

Triethylamine (0.83 g) and methanesulfonyl chloride (0.89 g) were added to a THF solution (10 mL) of 3-hydroxyphthalic anhydride (1.22 g) under ice cooling and the mixture was stirred at room temperature for 8 hours. After finishing the reaction, ether (20 mL) was added and the mixture was washed consecutively with water and saturated aqueous solution of sodium chloride and dried with anhydrous sodium sulfate. After distilling off the solvent under reduced pressure, the crude product was washed with a mixed solvent of ether and n-hexane to obtain 3-methanesulfonyloxyphthalic anhydride (1.75 g) having the melting point of 134–140° C.
