The title compound was prepared using the procedure described in Example 3(h) starting from 3-(1-trityl-1H-imidazol-4-yl)-1H-pyrazole-5-carboxylic acid (0.875 mmol, 0.368 g) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chloro-6-fluorobenzonitrile (0.673 mmol, 0.250 g) using HBTU (0.067 mmol, 0.026 g) instead of HOBt. DCM (4 ml) was used as the solvent. The reaction mixture was diluted with DCM and washed with 1 M Na2CO3 and water. The separated organic phase was dried, filtered and evaporated to give 0.511 g of crude product. Another crude batch (931 mg) was combined here and purified first by trituration in ACN and then by flash chromatography to give 0.095 g of the product. 1H-NMR (400 MHz, DMSO-d6): δ 1.18 (d, 3H), 4.13-4.53 (m, 3H), 6.64 (s, 1H), 6.98 (d, 1H), 7.09-7.19 (m, 4H), 7.35-7.51 (m, 9H), 7.52-7.57 (m, 1H), 7.70-7.76 (m, 1H), 7.79-7.86 (m, 2H), 7.92 (s, 1H), 7.95 (s, 1H), 8.06-8.10 (m, 1H), 8.14-8.18 (m, 1H), 13.35 (bs, 1H).
