Procedure

N-[5-(3,5-Difluoro-benzyl)-1-trityl-1H-indazol-3-yl]-2-fluoro-5-formyl-benzamide (740 mg, 1.137 mmol) in dry dioxan (25 mL) was treated with 4N HCl in dioxan (2.8 mL). The reaction was stirred at room temperature for two days. The volatile components were evaporated to dryness and the residue was taken up with Et2O (10 mL), stirred for 1 hour, filtered with suction, washed with Et2O (10 mL), dried at 50° C. under vacuum to afford 358 mg of title compound as a white solid in 77% yield.
