Procedure
76.0 g of ethyl 3-cyclohexylpropionate are initially introduced into 200 ml of dimethylformamide at 0° to 5° C., and 24.6 g of sodium hydride (80% strength in oil) are added. After dropwise addition of 235 ml of ethyl formate, the mixture is stirred at 25° C. for 24 hours. The batch is stirred into 1.6 l of 10% strength HCl, extracted with 800 ml of methylene chloride and distilled. 34.2 g (41%) of ethyl 2-formyl-3-cyclohexylpropionate of boiling point 91°-95° C./1.25 mm are obtained.
