Procedure

17.1 g (0.1 mol) of ethyl N-allyl-N-(2-oxoethyl) -carbamate are heated under reflux overnight in a water separator with 10 g (0.1 mol) of azetidine-2-carboxylic acid in 200 ml of toluene. Unreacted amino acid is filtered off with suction, the filtrate is concentrated and the residue is distilled.

Workup

  1. filtrationUnreacted amino acid is filtered off with suction
  2. concentrationthe filtrate is concentrated
  3. distillationthe residue is distilled
