Procedure
113.3 g (790 mmol) of trifluoroacetic acid ethyl ester is added in drops to a solution consisting of 41.14 g (390 mmol) of 1,4,7-triazaheptane in 350 ml of tetrahydrofuran at 80° C. and under nitrogen. It is allowed to stir overnight at room temperature, concentrated by evaporation in a vacuum. The remaining oil is crystallized from hexane.
