Participants

Reaction Steps

20 g (48 mmole) 4-[phenylsulfonyloxy]phenethyl 1-benzenesulfonate, 11.7 g (95 mmole) p-hydroxybenzaldehyde and 13.27 g (96 mmole) potassium carbonate in 100 ml acetonitrile were refluxed over night. The precipitate was filtered off and the filtrate was evaporated in vacuo. Dichloromethane was added, the solid material was filtered off and the filtrate was evaporated in vacuo. The residue was purified by chromatography on silica gel using ethyl acetate:petroleum ether (1:2) as eluent to give 12 g (yield 65%) of 4-[2-(4-formylphenoxy)ethyl]phenyl 1-benzenesulfonate.
