Procedure: Trifluoroacetic acid ethyl ester (50 g; 0.35 mol) was dropped into a solution of diethylenetriamine (18 g; 0.175 mol) in THF (180 mL) at 0° C. in 1 h. After 20 h at room temperature, the mixture was evaporated to an oily residue (54 g). The oil was crystallized from Et2O (50 mL), filtered, washed with cooled Et2O (2×30 mL) and dried to obtain A as a white solid (46 g; 0.156 mol). Yield 89%. the mixture was evaporated to an oily residue (54 g) The oil was crystallized from Et2O (50 mL) filtered washed with cooled Et2O (2×30 mL) dried to obtain A as a white solid (46 g; 0.156 mol)
