Versuchsvorschrift
(Z)-5-fluoro-2-methyl-1-(4-methythiobenzylidene)-3-indenylacetic acid (70 mmol) in THF (500 ml) is allowed to react with oxalylchloride (2 M in CH2Cl2 ; 35 ml) under reflux conditions (24 hours). The solvent is evaporated to yield the title compound, which is used as such in the next step.
Aufarbeitung
- customThe solvent is evaporated
