The title compound was prepared using the procedure described in Example 3(h) starting from 1H,2′H-3,3′-bipyrazole-5-carboxylic acid (2.245 mmol, 0.4 g) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chloro-6-fluorobenzonitrile (1.871 mmol, 0.521 g) and using DMF (10 ml) as the solvent. Water was added to the reaction mixture and the mixture was extracted with EtOAc. The organic phase was washed with 2M Na2CO3, water and brine. The organic phase was dried, filtered and evaporated. The crude product was purified by flash chromatography and preparative HPLC, respectively. 0.1277 g of the title compound was obtained. 1H-NMR (400 MHz, DMSO-d6): δ 1.19 (d, 3H), 4.27-4.56 (m, 3H), 6.64 (bs, 1H), 6.84 (bs, 1H), 6.98 (d, 1H), 7.77 (bs, 1H), 7.81-7.87 (m, 2H), 7.93-7.6 (m, 1H), 8.07 (br. s, 1H), 12.57-13.78 (m, 2H).
