실험 절차

153.9 g (1.29 mols) of thionyl chloride are poured onto 65.6 g (0.431 mol) of 3,4-methylenedioxybenzyl alcohol. The mixture is stirred for 90 minutes at ambient temperature (15°-25° C.) and the excess thionyl chloride is then evaporated. The residue is taken up in dimethylformainde (DMF) and the latter is then evaporated. Finally, the residue is taken up in 500 ml of DMF (it is not necessary to isolate the 3,4-methylenedioxybenzyl chloride thus obtained).
