Procedure

(2-tert-Butylcarbamoyl-ethyl)-carbamic acid tert-butyl ester (0.65 g, 2.64 mmol) is dissolved in trifluoroacetic acid (3.5 ml) and allowed to stir at room temperature under an inert atmosphere for 3 hours. The solvent is removed in vacuo to yield the titled compound as a TFA salt which is used crude in the next step:
