実験手順
The title compound was prepared using the method of Example 34(d) starting from imidazo[1,2-a]pyridine-2-carboxylic acid (0.853 g, 5.26 mmol) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chloro-6-fluorobenzonitrile (1.0 g, 3.59 mmol). The product was purified by flash chromatography and recrystallization from acetonitrile/water, respectively. Yield 39.0%. 1H-NMR (400 MHz; DMSO-d6): δ 1.13 (d, 3H), 4.35 (dd, 1H), 4.43 (dd, 1H), 4.47-4.57 (m, 1H), 6.96-7.01 (m, 1H), 7.02 (d, 1H), 7.34-7.40 (m, 1H), 7.60 (dd, 1H), 7.89 (d, 1H), 7.93 (dd, 1H), 7.97 (s, 1H), 8.32 (d, 1H), 8.55-8.58 (m, 1H), 8.61 (d, 1H).
