Versuchsvorschrift

A solution of 1-(2-carbamoylethyl)-4-cyanopyridinium chloride (21.2 g; 0.1 mole) dissolved in 15 ml of deionized water was prepared and charged to the dropping funnel. This solution was then added to the pyrrolidine/sodium hydroxide solution at a rate which permitted maintenance of the reaction temperature with stirring at below 5° C. It was held there for an additional hour, after which 14 g (0.175 mole) of a 50% (w/w) sodium hydroxide solution was added dropwise with continued maintenance of the reaction temperature below 5° C. (approximately 45 minutes). The mixture was then heated to reflux and maintained for two hours and then allowed to cool.
