Reaction Steps

19.3 g of β-pyrrolidino-acrylonitrile were added at -10° C. to 30 g of pyrrolidino-butene from A4 in 50 ml of chloroform. The mixture was allowed to warmto RT, and 50 ml of acetic acid were added dropwise. After stirring at RT for 15 hours, the mixture was cooled to -10° C., and dry hydrogen chloride gas was introduced. Aqueous workup gave 2-chloro-5-ethylpyridine as the main product.
