反応手順

A mixture of 65.5 g (0.5 mol) of ethyl N,N-dimethylglycinate, 44.6 g (0.5 mol) of N,N-dimethylethanolamine and 0.82 g of dibutyltin oxide was heated at about 130° C. The ethanol by-product was collected in a Dean-Stark trap. When the rate of ethanol evolution and amount of ethanol collected showed that the reaction was essentially complete, the reaction was heated at about 180° C. until ethanol evolution ceased. The liquid product was purified by distillation at reduced pressure to provide 2-(N,N-dimethylamino)ethyl N,N-dimethylaminoacetate.
