50 g (0.5 mol) of phosgene were condensed into a stirred apparatus fitted with a -78° C. dry-ice condenser. 50.5 g (0.4 mol) of cyclohexyl vinyl ether were subsequently added dropwise at 20° C. over the course of 3 hours. The mixture was subsequently stirred at 50° C. for a further 5 hours. The excess phosgene was expelled by means of nitrogen, and the crude product was worked up by distillation at 110° C./2.5 mbar, giving 66.4 g (88%) of valuable product.
