Reaction Steps

A mixture of 1-benzenesulfonyl-4-chloro-5-nitro-1H-pyrrolo[2,3-b]pyridine (10 g, 29.6 mmol), cyclohexyl amine (3.4 ml, 30.0 mmol), diisopropylethylamine (11 ml, 65.0 mmol) in propan-2-ol (150 ml) was heated at 80° C. for 14 h. The mixture was then cooled to 25° C. and stirred for 6 h. The resulting yellow solid was collected by vacuum filtration, washed with propan-2-ol (1×30 ml), and was air-dried to afford (1-benzenesulfonyl-5-nitro-1H-pyrrolo[2,3-b]pyridin-4-yl)-cyclohexyl-amine (10.45 g, 90%). LCMS (Method G, ESI): RT=1.33 min, m+H=401.2; 1H NMR (400 MHz, DMSO) δ 8.93 (s, 1H), 8.91 (s, 1H), 8.13 (d, J=7.6 Hz, 2H), 7.82 (d, J=4.1 Hz, 1H), 7.77 (t, J=7.4 Hz, 1H), 7.66 (t, J=7.8 Hz, 2H), 6.99 (d, J=4.2 Hz, 1H), 4.12-4.01 (m, 1H), 2.02-1.93 (m, 2H), 1.76-1.54 (m, 3H), 1.55-1.38 (m, 4H), 1.33-1.20 (m, 1H).
