✦ Synopsis

Pyridines

2-[ (Chloroacetyl)amino]acrylonitriles 1 and 3-[ (chloroacety1)-ridinones 8. Analogously to other orfho-diamines, the substi-

(1.92 g, 20 mmol) and dry K2C03 (4.2 g, 30 mmol) in dioxane (15 ml) were stirred at 6 0 T , and chloroacetyl chloride (3.4 g, 30 mmol) was added dropwise within 1 h to the reaction mixture. After additional stirring at 60°C for 1 h and cooling to room temp. the reaction mixture was poured into water (100 ml). Filtration and washing with water afforded crude l a (2.2 g, 58%), m.p. 51-54°C (benzene). -C7H9C1N20 .
