Procedure

To a solution of 6-amino-1-benzyl-N-(3,4-difluorobenzyl)-2-isopropyl-1H-indole-3-carboxamide (Compound 125, 18 mg, 0.042 mmol) in CH2Cl2 (1 ml) was added i-PrCOCl (8.7 μl, 0.089 mmol) and DMAP (10 mg, 0.089 mmol). The reaction was stirred at room temperature for 2 h, diluted with EtOAc, washed with aqueous Na2CO3 and 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.
