Procedure
This compound was prepared in a similar manner to (E)-2-(4,6difluoro-1-indanylidene)acetyl chloride in Example 5f by substituting (E)-2-(4-fluoro-1-indanylidene)acetic acid (5.77 g, 0.03 mol) for (E)-2-(4,6-difluoro-1-indanylidene)acetic acid. The resulting solution was concentrated in vacuo, and the residue was used without further purification.
