Versuchsvorschrift

(3S,8S)-3-[3-(3,4-Dichloro-benzyloxy)-phenyl]-8-{(S)-2-[4-(2,3-dimethyl-pyridin-4-yl)-phenyl]-1-methoxycarbonyl-ethylcarbamoyl}-2,3,8,9-tetrahydro-6H-[1,4]dioxino[2,3-g]isoquinoline-7-carboxylic acid tert-butyl ester (152 mg) was taken in 3 mL anhydrous DCM and cooled 0° C., HCl (0.75 mL, 4N in dioxane) was added and stirred at room temperature for 1 hour. All volatiles are evaporated and the residue was suspended in a 2N Na2CO3 solution and then extracted with EtOAc. The ethyl acetate layer was separated and washed with brine, and then dried (Na2SO4). The solvent was evaporated (105 mg). LCMS (m/z): 753.
