Reaktionsschritte

A solution of 4-carboxybenzaldehyde (30.0 g, 0.200 mol) in toluene (300 mL) was treated with thionyl chloride (28.6 g, 0.240 mol) and DMF (1.0 mL). The reaction mixture was heated at 100° C. for 2 h, during which time the solids dissolved to yield a pale yellow colored solution. The reaction mixture was cooled to 0° C. to yield a solution of the title compound in toluene, which was used without further manipulation.
