Reaction Steps

The title compound was prepared using the procedure described in Example 3(h) starting from 6-nitroimidazo[1,2-a]pyridine-2-carboxylic acid (0.551 mmol, 0.114 g) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chloro-6-fluorobenzo-nitrile (0.459 mmol, 0.128 g). DMF (4 ml) was used as the solvent and HBTU (0.046 mmol, 0.017 g) was used instead of HOBt. The crude product was purified by preparative HPLC. 0.0405 g of the title compound was obtained. 1H-NMR (400 MHz, MeOH-d4): δ 1.37 (d, 3H), 4.30-4.37 (m, 1H), 4.38-4.46 (m, 1H), 4.59-4.72 (m, 1H), 6.72 (d, 1H), 7.54 (d, 1H), 7.68 (d, 1H), 7.72 (s, 1H), 7.78 (d, 1H), 8.15-8.21 (m, 1H), 8.38 (s, 1H), 10.40-10.44 (m, 1H).
