Procedure
To a solution of N-[5-(3,5-difluoro-benzyl)-1-trityl-1H-indazol-3-yl]-4-(4-methyl-piperazin-1-yl)-2-nitro-benzamide (28.5 mg, 0.04 mmol) in dioxane (1 mL), 4 M HCl in dioxane (0.1 mL) was added and the mixture was stirred at room temperature for 1 hour. After concentration the residue was suspended in diethyl ether/MeOH 1:1, stirred for 20 min., filtered, washed with the same solvent mixture and dried. The desired product was obtained as hydrochloride derivative (19 mg, 87%).
