Procedure

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 (2.493 mmol, 1048 mg) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chloro-benzonitrile (1.918 mmol, 500 mg) using a mixture of DCM (10 ml) and DMF (1 ml) as the solvent. HBTU (0.384 mmol, 145 mg) was used instead of HOBt. The reaction mixture was diluted with DCM and washed with 1 M Na2CO3 and water. The separated organic phase was dried, filtered and evaporated. 1.637 g of the title compound was obtained. 1H-NMR (400 MHz, DMSO-d6): δ 1.12 (d, 3H), 4.17-4.52 (m, 3H), 6.75 (bs., 1H), 6.92 (d, 1H), 7.12-7.19 (m, 7H), 7.35-7.53 (m, 12H), 7.80 (d, 1H), 7.97 (bs, 1H), 8.04 (s, 1H), 8.21 (d, 1H), 13.38 (bs., 1H).
