Versuchsvorschrift

A solution of 8-{[(2-chloropyridin-3-yl)carbonyl]amino}-1-(4-ethynylphenyl)-4,5-dihydro-1H-benzo[g]indazole-3-carboxamide (557 mg, 1.19 mmol) in DMF-DMSO (20 mL-1 mL) was treated at RT with H2 (5 psi) and Pd-CaSO4 (5%, 100 mg) for 12 min. The mixture was filtered through celite pad, concentrated and added water. The solid product was collected via filtration, washed with water and ether, and dried to give product (262 mg, 47%). 1H NMR was consistent with its structure.
