Abstract: A process for the acetylation of the sterically non- hindered amino group in diamines (I) with a sterically hindered amino group and another non-hindered amino group comprises reacting the diamine with ketene. Preferably the reaction is carried out at -30 to 65 degrees C in an aprotic solvent, preferably THF. The sterically hindered amine function is part of a heterocycle. Preferred (I) is TAD.
