Versuchsvorschrift

(Z)-5-methoxy-2-methyl-1-(p-methylsulfonylbenzylidene)-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

  1. customThe solvent is evaporated
