Abstrakt: Efficient trapping of dimethylamine was the key to success in the transamination of 1,1-dimethyl-4-oxopiperidinium iodide with tert-butylamine to afford 1-tert-butylpiperidin-4-one in high yield. The use of sodium acrylate was found to provide an elegant way to both trap dimethylamine and provide a convenient method to allow purification in the subsequent extraction.
