Reaction Steps

30 g of 2-(2,4,5-trimethylphenyl)-malonic acid were suspended in 60 ml of toluene at 50 to 60° C. and 62.5 ml of thionyl chloride were added dropwise. The mixture was then heated at 90 to 100° C. for 15 hours. It was then cooled, the volatile constituents were driven off with an inert gas and the excess thionyl chloride was distilled off. 30.6 g of 2,4,5-trimethylphenylchlorocarbonyl ketene were isolated as the residue.
