A mixture of 3-Amino-cyclopentanol hydrochloride (0.9 g, 5.9 mmol), 1-Benzenesulfonyl-4-chloro-5-nitro-1H-pyrrolo[2,3-b]pyridine (2.0 g, 5.9 mmol) and diisopropylethylamine (2.3 g, 17.7 mmol) in ethanol (100 mL) was stirred at 80° C. for 3 hours. The reaction mixture was purified by column chromatography (Hexanes/ethyl acetate=3:1) to give 2.6 g (76%) of 3-(1-Benzenesulfonyl-5-nitro-1H-pyrrolo[2,3-b]pyridin-4-ylamino)-cyclopentanol; 1H NMR (400 MHz, CDCl3) δ: 9.56 (s, 1H), 9.54 (s, 1H), 8.19-8.16 (m, 2H), 7.62-7.56 (m, 4H), 6.82-6.81 (m, 1H), 4.56-4.50 (m, 2H), 2.25-1.96 (m, 6H).
