Reaction Steps

6.8 g (0.10 mole) of imidazole and 15.3 ml (0.11 mole) of triethylamine are stirred in 100 ml of tetrahydrofuran. While cooling at 25°-30° C., a solution of 23.1 g (0.11 mole) of 2,6-dichloroisonicotinic acid chloride in 20 ml of tetrahydrofuran is then added dropwise, triethylamine hydrochloride separating. This is filtered off with suction and the filtrate is concentrated to 26.4 g of crude product. Recrystallisation from ethyl acetate yields 20.1 g (83% of the theoretical amount) of pure substance; m.p. 148°-151° C.
