Versuchsvorschrift

A mixture of commercially available 2-(3-nitrophenyl)acetic acid [CAS no. 1877-73-2] (25.8 g, 142 mmol, Eq: 1.00) and thionyl chloride (25.4 g, 15.5 ml, 214 mmol, Eq: 1.5) in toluene (141 ml) and DMF (208 mg, 221 μl, 2.85 mmol, Eq: 0.02) was stirred at 80° C. for 2 h. The hot solution was filtered through a Sartorius filter, the filtrate was evaporated and dried in HV to give the 2-(3-nitrophenyl)acetyl chloride (28.12 g, 141 mmol, 98.9% yield) as a yellow solid, which was used without further purification.
