9.22 g lauroylchloride dissolved in 46 ml dioxane were slowly added to 6.72 g glutamine and 13.94 g triethylamin in 92 ml water and 92 ml dioxane, the temperature being 0° C. After stirring at room temperature for 1 hour, the dioxane was evaporated and the remaining solution was acidified to pH 1 with HCl.
