Procedure
40.7 g of ethyl 3-cyclopentylpropionate are placed in 400 ml of DMF at from 0° to 5° C., 14.4 g of sodium hydride (80% in oil) are added. After dropwise addition of 200 ml of ethyl formate, the mixture is stirred at 25° C. for 24 h. The mixture is stirred into 1.6 l of 10% HCl, extracted with 800 ml of methylene chloride and distilled. 19.7 g (41%) are obtained of ethyl 2-formyl-3-cyclopentylpropionate of boiling point 117° C./12 min.
