    • Compound 22 was synthesized by Wittig coupling with p-fluorobenzaldehyde to yield ethyl p-fluorocinnamate. Reduction with DiBAl resulted in mainly p-fluorocinnamyl alcohol. Swern oxidation of the alcohol resulted in a complex mixture, which was difficult to purify by silica gel chromatography.
