Versuchsvorschrift

To a solution of 2-Methoxycarbonylamino-3-(tetrahydro-pyran-4-yl)-propionic acid methyl ester (0.11 g, 1.1 mmol) in THF (3.3 mL) and MeOH (1.1 mL) at 0° C. (external, ice bath) was added aqueous LiOH (1 M, 0.88 mL, 0.88 mmol). The solution was stirred at room temperature for 18 h and concentrated to provide 2-Methoxycarbonylamino-3-(tetrahydro-pyran-4-yl)-propionic acid which was used crude in the next step. LCMS-ESI+: calc'd for C10H17NO5: 231.11 (M+); Found: 231.99 (M+H+).
