Reaction Steps
29 g (0.14 mol) of 4-ethoxycarbonylmethoxybutyric acid chloride are dissolved in 290 ml of tetrahydrofuran and the solution is hydrogenated under normal pressure at 10°-15° C. by addition of 5.8 g of 5% Pd/C and 18 ml of 2,6-lutidine. Upon cessation of hydrogenation, the catalyst is removed by filtration and the filtrate is concentrated by evaporation. Distillation of the crude product gives 4-ethoxycarbonylmethoxybutanal as a clear colourless liquid of b.p. 72°-74° C./2.10-2 torr.
