実験手順
General Procedure B. To a solution of 1-benzyl-N-(3,4-difluorobenzyl)-6-hydroxy-2-isopropyl-1H-indole-3-carboxamide (Compound 8, 18mg, 0.041mol) in pyridine (1 ml) was added dimethylcarbamyl chloride (40 μl, 0.41 mmol) and stirred at room temperature overnight. The reaction was quenched with water, extracted with ethyl acetate. The combined organic layer was washed with water, 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 white solid (17 mg, 82%).
