Versuchsvorschrift
Oxalyl chloride (211 μl; 2.23 mmol; 1.2 eq.) was added to a suspension of 3-pyridineacetic acid (255 mg; 1.86 mmol; 1.0 eq.) in DCM/DMF (5 mL:3 μL) maintained at 0° C. under nitrogen atmosphere. The reaction mixture was then stirred at rt for 1 h. It was then concentrated under reduced pressure. The solid obtained was used as such in amidation reactions.
