346.8 g 3-(2-Chloroethoxy)-2-ethyl-acrylic acid methyl ester was hydrogenated in 1200 ml methanol in the presence of 27 g 5% palladium-carbon catalyst at atmospheric pressure. The amount of hydrogen required to saturate the double bond was absorbed within approximately 90-120 minutes, whereupon the catalyst was filtered off, and the filtrate was partly evaporated. The residue was distilled in a vacuum to produce 305 g 3-(2-chloroethoxy)-2-ethyl-propionic acid methyl ester (87% yield) boiling at 110°-112° C./14 torr.
