実験手順

To a solution of 1-benzyl-N-(3,4-difluorobenzyl)-2-isopropyl-6-methoxy-1H-indole-3-carboxamide (Compound 7, 452 mg, 1.0 mmol) in CH2Cl2 (20 ml) at 0° C. was added BBr3 (1.0 M in CH2Cl2, 3.0 ml, 3.0 mmol) dropwise. The reaction was stirred for 1 h at 0° C. and 1 h at room temperature, quenched with ice, extracted with EtOAc, the organic layer was washed with brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by chromatography on silica gel (0→50% EtOAc-hexanes) to yield the title compound as a yellow solid.
