Versuchsvorschrift

2-(1-(tert-Butoxycarbonyl)azetidin-3-yl)acetic acid (0.308 g, 1.43 mmol) was dissolved in 5 mL dichloromethane and was stirred at room temperature. Trifluoroacetic acid (1.47 mL) was added dropwise to the reaction mixture at 0° C. The reaction mixture was allowed to stir at room temperature for 2 h. Trifluoroacetic acid was removed in vacuo to give 2-(azetidin-3-yl)acetic acid trifluoroacetic acid salt. 1H-NMR (400 MHz, CDCl3) δ ppm 4.18-4.13 (m, 2H), 3.93-3.88 (m, 2H), 3.25-3.19 (m, 1H), 2.71 (d, 2H, J=7.6 Hz).
