Versuchsvorschrift

A solution of dimethyl sulfoxide (3 ml, 41.4 mmol) in dichloromethane is added to a solution of oxalyl chloride (20.7 mmol, 1.8 ml) in dichloromethane (55 ml). A solution of (2-heptyloxy-4-iodophenyl)methanol (6.55 g, 18.8 mmol) in 25 ml of dichloromethane is added dropwise to the solution previously obtained, at −78° C. The mixture is stirred until the temperature returns to room temperature. The organic phase is acidified with a 2N hydrochloric acid solution. The desired product is extracted by addition of ethyl acetate. The organic phase is washed with water, dried with magnesium sulfate and concentrated using a rotary evaporator. 6.5 g (100%) of the expected compound are recovered in the form of a yellow solid.
