HCID 148366043-(2,2-Dimethylpropylideneamino)-pyrrolidine

Procedure

12.1 g (0.1 mol) of 71% strength pivalaldehyde, initially introduced into the reaction vessel and 8.6 g (0.1 mol) of 3-aminopyrrolidine are added dropwise at 20° C. to 30° C., while cooling in a water bath. The mixture is subsequently stirred at room temperature for 1 hour and is then distilled. Yield: 13.5 g (85% of theory), boiling point: 63° C.-65° C./10 to 12 mbar; content: 97%.
