Reaction Steps
13.2 g of β-dimethylamino-acrylonitrile were added dropwise at 30° C. to a solution of 22 g of DMF/HCl adduct in 100 ml of DMF. Following an after-reaction time of 2 h, this solution was added dropwise, while passing in HCl, to a solution, saturated at 50° C., of HCl gas in DMF. The temperature was maintained at 50° C. by cooling. After conventional work up (40 ml of water), 2-chloro-5-cyanopyridine was obtained in 77.7% of the theoretical yield, based on the C3 unit employed.
