Versuchsvorschrift
To a solution of (S)-tert-butyl (pyridin-2-yl(4-(trifluoromethyl)phenyl)methyl)carbamate (1.83 g, 5.19 mmol) in DCM (12 mL) was added TFA (3.86 mL, 51.9 mmol). The resulting mixture was then stirred at rt for 1 h. The mixture was then concentrated and dried to give the title compound as a yellow oil which was used without further purification in the amide coupling step.
