Example 16
2-(Chloromethyl)-1,3-dimethylbenzene
91.4 g [0.768 mol] of thionyl chloride in 100 ml of toluene are initially charged, heated to 72° C. and a solution of 100 g of 2,6-dimethylbenzyl alcohol of a purity of 74.7% in 700 ml of toluene is added dropwise thereto within an hour.
Further stirring is subsequently carried out for one hour at 72° C.
The excess thionyl chloride is distilled off, the residue is filtered over some Celite and concentrated under reduced pressure.
This gives 107.2 g of a brown oil which, according to GC/MS analysis, contains 71.0% of the title compound, which corresponds to a yield of 89.7% of theory.
GC/MS: m/e=154 (M+, 35Cl, 17%), 119 (M-35, 100%),
