Sarcosine → HCID 54274964, compound

Participants

Reaction Steps

11.25 g (0.15 mol) of sarcosine and 3 g (0.075 mol) of NaOH are dissolved in 210 ml of water. While cooking the solution in a water bath 9 g (0.225 mol) of NaOH, dissolved in 45 ml of water, and 29.6 g (0.15 mol) of mesityleneacetyl chloride are added synchronously dropwise, during which addition the temperature is kept at <40 ° C. After 1 hour the mixture is acidified with concentrated HCI at 0° to 20° C., filtered off and the filtrate is dried in vacuo over P2O5 at 70° C. 37.1 g (99.3 % of theory) of N-(2,4,6-trimethyl-phenyl-acetyl)-sarcosine of a melting point of 140° C. are obtained.
