Procedure

The 4′-methyl-5-(2-oxo-2,3-dihydro-indol-1-yl)-biphenyl-3-carboxylic acid from step 3 was added to DMF (3 mL), together with C-(5-methyl-pyrazin-2-yl)-methylamine (0.1 mL), HOAt (15 mg, catalytic amount), NMM (0.4 mL) and EDCI (200 mg). The reaction mixture was stirred overnight at room temperature, then partitioned between water and ethyl acetate. The organic layer was separated and concentrated under reduced pressure, and the resulting residue was purified by preparative thin layer chromatography (7% MeOH in dichloromethane) to give 20 mg (5% overall) of 4′-methyl-5-(2-oxo-2,3-dihydro-indol-1-yl)-biphenyl-3-carboxylic acid (5-methyl-pyrazin-2-ylmethyl)-amide, MS (M+H)=449.
