実験手順
The necessary intermediate 4-Cyclopropyl-3-ethoxy-benzaldehyde was prepared as described in example 158, but using 3-ethoxy-4-iodo-benzaldehyde (synthesized from 3-ethoxy-4-iodo-benzoic acid ethyl ester (CAS NO. 741699-04-7) by DIBAL-H reduction followed by MnO2 oxidation) as starting material, as light brown oil.
