実験手順

A suspension of 4-[4-amino-2-(cyclopropylmethoxy)-3-nitrophenyl]-6-methyl-1-[(4-methylphenyl)sulfonyl]-1,6-dihydro-7H-pyrrolo[2,3-c]pyridin-7-one (0.119 g, 0.234 mmol) in ethyl acetate (1.2 mL) and methanol (1.2 mL) was treated with saturated aqueous ammonium chloride solution (0.274 mL, 4.09 mmol). The mixture was cooled to 0° C., treated with zinc (0.122 g, 1.87 mmol) in two portions over 5 min, stirred at RT for 30 min and heated at 55° C. for 1 h. The reaction mixture was diluted with dichloromethane, filtered through a Celite pad, and the solids were washed with dichloromethane. The filtrate was concentrated to give a residue. The residue was dissolved in dichloromethane (30 mL), washed with saturated sodium bicarbonate solution (20 mL), dried with sodium sulfate, filtered, and concentrated to give the desired product that was used without further purification. LCMS calculated for C25H27N4O4S (M+H)+: m/z=479.2. found: 479.1.
