Procedure

64 g (0.4 mole) of 2-chloromethylene-3-ethyl-3-methyl-tetrahydrofuran are saturated with hydrogen chloride gas at 10° to 20° C., while cooling with ice. After the mixture has been left to stand at room temperature for 2 hours, excess hydrogen chloride is stripped off and the residue is distilled. 60 g (81% of theory) of 1,5-dichloro-3-ethyl-3-methyl-2-pentanone of boiling point 92°-101° C./0.05 mbar are obtained. ##STR102##
