実験手順

Bromoacetaldehyde diethylacetal, 52.4 g (0.26 mol), was mixed carefully with approximately 70.7 g (0.967 mol) diethylamine and stirred at 40° C. overnight. The reaction mixture was concentrated under reduced pressure and the residue dissolved in water and basified with cold 5 N sodium hydroxide. The reaction mixture was extracted twice with diethyl ether, dried over anhydrous sodium sulfate and concentrated under reduced pressure to give a tan oil. Distillation gave 35.8 g (72.8%) diethylaminoacetaldehyde diethylacetal as a clear liquid. B.p. 65°-75° C. @1.0 mmHg.
