Reaktionsschritte
α-Chlorobenzyl chloroformate (1 g) was added to an ice-cold solution of triethyleneglycol monomethylether (0.7 ml) in dichloromethane (5 ml) followed by pyridine (0.43 ml) at such a rate that the temperature was kept below 10° C. After stirring overnight at room temperature the reaction mixture was washed twice with 0.5 M HCl followed by water and aqueous sodium bicarbonate. Drying over magnesium sulfate, filtration, evaporation in vacuo followed by chromatography on silica gel with hexane/ethyl acetate (1:1) as eluent gave the title compound as a colourless oil.
