Procedure

To a suspension of N-hydroxy-1-methyl-3-[1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-2-yl]-1H-indole-5-carboxamidine [0.7 g, Reference Example 26] in toluene (30 mL) at ambient temperature under nitrogen was added acetic anhydride (0.467 g). The reaction mixture was heated at reflux for 4.5 hours then filtered. The filtrate was evaporated to give the title compound (0.32 g) as a dark red oil which was used immediately without further purification.
