Versuchsvorschrift
A mixture of 25 g. of o-chloroacetophenone and 25 ml. of dimethylformamide dimethylacetal is refluxed for 16 hours. Evaporation gives a thick red-brown oil which is dissolved in methylene chloride and this solution passed through a hydrous magnesium silicate column. Evaporation of solvent gives an oil which is then purified by bulb to bulb distillation.
