Versuchsvorschrift

3-(Benzyloxy)-5-methoxybenzoic acid (162) (2.57 g, 0.01 mmol) and thionyl chloride (4.80 g, 0.04 mmol) were suspended in 200 mL of dry toluene. The reaction mixture was stirred for 30 min and then dimethyl formamide (3 drops) was added. The mixture was stirred for 24 h and then evaporated to dryness. The residue was directly used for the next step without further purification.
