To a suspension of 2-[2,6-dichloro-4-(4-methoxybenzyloxy)-phenyl]-1H-indole-6-carboxylic acid quinolin-2-ylamide (200 mg, 0.352 mmol) in DCM (7.5 mL) and MeOH (2.5 mL) was added 4 M HCl in dioxane (7.5 mL) and the mixture was stirred for 2.5 hr. The reaction was concentrated under reduced pressured and the concentrate partitioned between EtOAc (150 mL) and sat NaHCO3 (30 mL). The organic phase was dried over Na2SO4 and the solvent evaporated. The residue was triturated with DCM to afford the title compound as an orange solid.
