실험 절차
(S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chloro-6-fluorobenzonitrile (0.22 g, 0.55 mmol) was coupled with 3-acetyl-1H-pyrazole-5-carboxylic acid (0.17 g, 1.11 mmol) using the method of Example 34(d). Crude product was purified by CombiFlash (column: C-18, eluent: 0-100% MeCN in water) to yield 47 mg (21%) of the title compound. 1H-NMR (400 MHz; MeOD): δ 1.28 (d, 3H), 2.51 (s, 3H), 4.31 (dd, 1H), 4.41 (dd, 1H), 4.52-4.61 (m, 1H), 6.79 (d, 1H), 7.23 (s, 1H), 7.67 (d, 1H), 7.70 (d, 1H), 7.83 (m, 1H).
