To a solution of 6-amino-N-(3,4-difluorobenzyl)-2-isopropyl-1-(pyridin-2-ylmethyl)-1H-indole-3-carboxamide (Compound 182, 48 mg, 0.11 mmol) in CH2Cl2 (1 ml) was added chloroethyl isocyanate (10 μl, 0.12 mmol). The reaction was stirred at room temperature for 16 h, and the solvent was removed. To the residue was added H2O and the mixture was heated at 80° C. for 3 h, diluted with EtOAc, washed with aqueous K2CO3 and brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by chromatography on silica gel (0→100% EtOAc-hexanes) to yield the title compound.
