Procedure

To a solution of 6-amino-N-(3,4-difluorobenzyl)-2-isopropyl-1-(pyridin-2-ylmethyl)-1H-indole-3-carboxamide (Compound 182, 64 mg, 0.15 mmol) in toluene (2 ml) was added 1,4-dibromobutane (19 μl, 0.16 mmol) and i-Pr2NEt (77 μl, 0.44 mmol). The reaction was heated at 110° C. for 16 h, and was purified directly by chromatography on silica gel (0→100% EtOAc-hexanes) to yield the title compound.
