Reaction Steps

A solution of 4-[3,4-diamino-2-(2,4-difluorophenoxyl)phenyl]-6-methyl-1-[(4-methylphenyl)sulfonyl]-1,6-dihydro-7H-pyrrolo[2,3-c]pyridin-7-one (0.040 g, 0.074 mmol) in acetic acid (0.1 mL, 3 mmol) was treated with water (0.37 mL, 21 mmol) followed by sodium nitrite (0.026 g, 0.37 mmol) and stirred at 20° C. for 30 min. The reaction mixture was diluted with ethyl acetate and water. The organic layer was washed with saturated sodium bicarbonate (2×) and brine, dried with magnesium sulfate, filtered, and concentrated to give the desired product (32 mg, 78%) as a crude brown residue that was used immediately without further purification. LCMS calculated for C27H20F2N5O4S (M+H)+: m/z=548.1. found: 548.1.
