Procedure

190 g of 3-chloro-2-methyl-alpha,alpha-dimethylbenzyl alcohol are refluxed with 1.5 l of toluene and 370 g of oxalic acid under a water separator until no more water separates off. The oxalic acid is filtered off under suction and the filtrate is washed with sodium bicarbonate solution, dried over sodium sulfate and evaporated down. Fractional distillation of the residue gives 91.5 g of the desired compound, which is listed in Table 1 as Example 2.
