Procedure

54 g of 4-[2,6,6-trimethyl-cyclohex-2-en-1-yl]-3,4-epoxy-2-butanone-oxime, which can be prepared as indicated above, in 500 ml of benzene were refluxed in the presence of 2 g of p-toluenesulphonic acid for about 4 hours. The water formed in the course of the reaction was removed as it formed by azeotropic distillation.
