Participants

Reaction Steps

6-Chloronicotinic acid (0.5 g, 3.17 mmol) and dimethyl amine 10 ml, 40% in water) were heated in a sealed pressure vessel at 130° C. for 6 h. The solvent was then removed and the residue was taken up in water and the pH was adjusted to 4–5. Extraction with dichloromethane yielded the pure intermediate depicted above (0.1 g, 20%).
