Versuchsvorschrift
To methyl 2-(3-acetyl-5-(benzyloxy)-1H-indazol-1-yl)acetate (3.70 g, 10.9 mmol) in THF (80 mL) was added Pd/C (10%, 400 mg). The reaction mixture was stirred at 50° C. overnight under a H2 atmosphere. The reaction mixture was filtered over a pad of Celite and washed with CH2Cl2, then volatiles were evaporated to give the title compound. MS (LC/MS): 248.9 [M+H]+, 271.0 [M+Na]+; tR (HPLC conditions c): 3.36 min.
