To a solution of 1-benzyl-N-(3,4-difluorobenzyl)-6-(hydroxymethyl)-2-isopropyl-1H-indole-3-carboxamide (Compound 52, 340 mg, 0.759 mmol) in CH2Cl2 (10 ml) at 25° C. under argon was added molecular sieve powder (300 mg), NMO (267 mg, 2.28 mmol), TPAP (26 mg, 0.08 mmol). The reaction was stirred for 10 minutes, then concentrated in vacuo. The residue was purified by chromatography on silica gel (0→25% EtOAc-hexanes) to yield the title compound as a light yellow solid.
