Procedure

The title compound was prepared using the procedure described in Example 3(h) starting from 2-bromo-1H-imidazole-4-carboxylic acid (5.75 mmol, 1.099 g) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (3.84 mmol, 1 g) using DMF (10 ml) as the solvent. DCM and water were added, the phases were separated and the water phase was extracted with DCM. The combined organics were washed three times with water. The DCM phase was dried, filtered and evaporated. The crude product was purified by flash chromatography and preparative HPLC, respectively. 37.8 mg of the title compound was obtained. 1H-NMR (400 MHz, DMSO-d6): δ 1.09 (d, 3H), 4.23-4.48 (m, 3H), 6.95 (d, 1H), 7.64 (s, 1H), 7.82 (d, 1H), 7.94-8.05 (m, 2H), 8.08 (s, 1H), 8.21 (d, 1H), 13.22 (bs, 1H).
