Versuchsvorschrift
Ethyl 5-((tert-butoxycarbonylamino)methyl)-1H-1,2,4-triazole-3-carboxylate (100 mg, 0.37 mmol) [Borg, S. et al., J. Org. Chem., 60:3112-3120 (1995)] was dissolved in CH2Cl2 (2 mL) and TFA (1 mL). After 1 h, this was concentrated to give ethyl 5-(aminomethyl)-1H-1,2,4-triazole-3-carboxylate, TFA (Int-XIV, 95 mg, 0.33 mmol, 90%); LCMS=171.1 [M+H]+; 1H NMR (400 MHz, methanol-d4) δ ppm 4.45 (2 H, q, J=7.12 Hz), 4.35 (2 H, s), 1.40 (3 H, t, J=7.15 Hz).
