Participants

Reaction Conditions

Reaction Steps

Methanesulfonyl chloride (0.67 mL) in DCM (2 mL) was added dropwise to a stirred solution at 0° C. of 2,2′-(1,3-phenylene)diethanol (1.30 g) and triethylamine (1.36 mL) in DCM (30 mL). The reaction mixture was stirred for 1 hour at 0° C. and then washed with water. The aqueous layer was re-extracted with DCM and the combined organic phases were dried, filtered and the solvent evaporated under reduced pressure. The crude product was purified by flash silica chromatography using 3% methanol in dichloromethane as solvent. Fractions containing the product were evaporated to dryness to afford the titled compound. Yield 0.52 g.
