Versuchsvorschrift

4-Chloroaniline (15 g, 117 mmol) and formic acid (25 mL, 663 mmol) were heated to reflux for 2 hours. The mixture was concentrated in vacuo. Saturated aqueous sodium hydrogen carbonate was added and the aqueous phase was extracted twice with ethyl acetate. The combined organic phases were dried over magnesium sulphate, filtered and concentrated in vacuo to give N-(4-chloro-phenyl)-formamide (17.6 g, 97%) as a grey crystalline compound.
