1H-Pyrazole-3,5-dicarboxylic acid monohydrate → (S)-5-(1-(3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl)propan-2-ylcarbamoyl)-1H-pyrazole-3-carboxylic acid

Participants

Reaction Steps

The title compound was prepared using the method of Example 54 but starting from 3,5-pyrazoledicarboxylic acid monohydrate (0.60 g; 3.84 mmol) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (1.0 g; 3.84 mmol). Crude product was purified by chromatography (CombiFlash, silica column, eluent: 0-100% MeOH/DCM) to obtain 29 mg (36%) of the title compound. 1H-NMR (400 MHz; d6-DMSO): δ 1.14 (s, 3H), 4.30-4.50 (m, 3H), 6.93 (d, 1H), 7.83 (s, 1H), 7.85-8.05 (m, 2H), 8.04 (s, 1H), 8.35-8.65 (m, 1H), 14.06 (s, 1H), 14.24 (s, 1H).
