The title compound was prepared using the procedure described in Example 3(h) using 1-(2,2-difluoro-ethyl)-2-methyl-1H-imidazole-4-carboxylic acid (0.926 mmol, 176 mg), (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chloro-6-fluorobenzo-nitrile (0.617 mmol, 172 mg) and only a catalytic amount of HOBt (0.062 mmol, 8.34 mg). DMF was used as the solvent. Water was added to the reaction mixture and the mixture was extracted it three times with DCM. The combined organics were washed twice with water. The organic phase was evaporated and the residue was purified by flash chromatography and preparative HPLC, respectively. 15.5 mg of the title compound was obtained. 1H-NMR (400 MHz, DMSO-d6): δ 1.07 (d, 3H), 2.36 (s, 3H), 4.23-4.55 (m, 5H), 6.19-6.51 (m, 1H), 7.02 (d, 1H), 7.53 (s, 1H), 7.86 (d, 1H), 7.90-7.95 (m, 1H), 8.00 (s, 1H), 8.12 (d, 1H).
