Procedure

A solution of 6-amino-1-benzyl-N-(3,4-difluorobenzyl)-2-isopropyl-1H-indole-3-carboxamide (Compound 125, 20 mg, 0.046 mmol) and ethyl4-bromobutanoate (13 μl, 0.092 mmol) in NMP (1 ml) was heated at 168° C. for 16 h, cooled to room temperature, diluted with EtOAc, 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.
