A vial was charged with 6-chloro-5-[4-(propan-2-yl)phenyl]-1H-indole-3-carbaldehyde, 1 mL acetonitrile, and 500 uL of a 1.0M solution of potassium permanganate in water. The vial was sealed and heated to 30° C. for 16 hrs. Sodium bisulfite (72 mg, 1.0 mmol) was then added and the reaction heated to 30° C. for 1 hr. The reaction was then filtered, and the solvent removed in vacuo. The residue was then purified by reverse phase prep HPLC to give the title compound. MS (AP−) 312 (M−H)−. RT=2.378 Column Xbridge C18 2.1×50 mm 5 μm, Temperature 50° C. Mobile Phase A=0.05% NH4OH in water. Mobile Phase B=100% acetonitrile.
