Versuchsvorschrift

146 g of lysine are dissolved in water and the solution is saturated with CO2 so as to obtain a 30% solution of lysine carbonate. Separately 226.6 g of 4-allyloxy-3-chlorophenylacetic acid are dissolved in 800 ml of isopropyl alcohol. The two solutions are joined by pouring the alcoholic solution into the aqueous solution with light stirring. Stirring is continued 5 hours at room temperature.
