2-Amino-N-[5-(3,5-difluoro-benzyloxy)-1H-indazol-3-yl]-4-[(3-dimethylamino-propyl)-methyl-amino]-benzamide (115 mg, 0.23 mmol) in pyridine (2.2 mL), cooled to 4° C., was treated with solid 1H-pyrrole-2-carbonyl chloride (34 mg, 0.27 mmol). The reaction was stirred until clear and left to room temperature over night. After removal of the volatiles, the crude was purified over silica gel to afford 90 mg of title compound in 66% yield.
