Procedure

To a solution of N-(2-aminophenyl)-1-methyl-4,5,6,7-tetrahydro-1H-pyrrolo[2,3-c]pyridine-2-carboxamide (1.0 eq) obtained in step IX of example 228, in DMF was added Et3N (3.0 eq.) followed by carbonic acid 3,4-dimethoxy-phenyl ester 4-nitro-phenyl ester (1.0 eq) and stirred at room temperature overnight. Reaction mixture was then quenched with water and extracted with dichloromethane, dried over anhydrous sodium sulfate, concentrated under reduced pressure to afford crude product, which, on purification by column chromatography afforded the title compound.
