1-Methylpyrrolidine → HCID 18371946, compound

Participants

Reaction Steps

Colorless 1-methylpyrrolidine, 195 g (2.3 mol), was added dropwise to 228 g (2 mol) of triethylaluminum at room temperature under nitrogen gas flow with stirring. After the addition of 1-methylpyrrolidine was completed, the resulting mixture was stirred for about 6 hours at room temperature to complete the reaction. 1-Methylpyrrolidine triethylaluminum was obtained after completion of the reaction, and was dried under vacuum at about 45° C. to give a colorless liquid. The dried colorless liquid compound was distilled under vacuum (10−2 torr) at 70° C., during which a colorless distillate was condensed inside a vessel cooled with dry ice. This first colorless distillate was purified according to the same procedure at 70° C. to give 354 g of the colorless liquid 1-methylpyrrolidine triethylaluminum having high purity.
