Using L-valine methyl ester hydrochloride as starting material, the synthesis of ( 2S)- 2- isopropyl- 1,4,7- trimethyl-1,4,7- triazacyclononane is described. Various standard Richman - Atkins cyclisation methods gave only poor yields in the key macrocyclisation step. Efficient macrocyclisation yields were, however, realised when an in situ sequential cyclisation method was developed.
