Reaction Steps

The title compound was prepared using the method of Example 53 but starting from 5-pyridin-2-yl-4H-pyrazole-3-carboxylic acid (38 mg; 0.20 mmol) and 4-(1-(2-aminoethyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (50 mg; 0.20 mmol). Crude product was purified by chromatography (CombiFlash, silica column, eluent: 0-100% MeOH/DCM) to obtain 19 mg (23%) of the title compound. 1H-NMR (400 MHz; d6-DMSO): δ 3.70-3.74 (m, 2H), 4.38 (t, 2H), 6.96 (d, 1H), 7.23-7.40 (m, 2H), 7.82-8.02 (m, 5H), 8.09 (s, 1H), 8.48, (broad s, 1H), 8.62 (d, 1H), 13.89 (broad s, 1H).
