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%).
