100 g (1.0 mol) of isobutyl vinyl ether are initially charged in a 500 ml stirred apparatus and heated to 50-55° C. 113 g (1.15 mol) of phosgene are subsequently introduced over a period of 11 h. After an extra reaction time of 1.5 h, the reaction mixture is stripped phosgene free at 50-55° C. by introduction of nitrogen. The mixture is subsequently allowed to cool to room temperature, and and [sic] 60.7 g (0.82 mol) of isobutanol are added dropwise. After the addition has ended, the resulting reaction mixture is rectified. This gives 150.4 g (75%) of isobutyl 3-isobutoxyacrylate of b.p. 97° C. at 2.5 mbar.
