Participants

Reaction Steps

A mixture of 2-{[(2-chloro-3-pyridinyl)carbonyl]amino}acetic acid (6.44 g, 30 mmol, prepared from glycine and 2-chloronicotinoyl chloride), 4-nitroacetophenone (2.48 g, 15 mmol), lead (IV) acetate (3.33 g, 7.5 mmol) and acetic anhydride in THF (30 ml) was heated at reflux for 4 days. The mixture was poured onto crushed ice, the solid filtered off, washed with water and dried. The brown solid was triturated twice with boiling ethanol and filtered off to give the title compound as a brown solid (1.07 g). δH (CDCl3), 8.57 (1H, dd, J 4.8, 2.1 Hz, PyH), 8.34-8,29 (3H, m, ArH+PyH), 8.05 (2H, d, J 9.1 Hz, ArH), 7.41 (1H, dd, J 7.9, 4.8 Hz, PyH) and 2.84 (3H, s, Me).
