1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → (R)-3-acetyl-N-(1-(3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl)butan-2-yl)-1H-pyrazole-5-carboxamide

Participants

Reaction Steps

The compound was prepared using the method of Example 34(d). The reaction was conducted in 4 ml of DCM at RT overnight using (R)-4-(1-(2-aminobutyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (0.249 g; 0.91 mmol), 3-acetyl-1H-pyrazole-5-carboxylic acid (0.140 g; 0.91 mmol), 0.24 ml of DIPEA, HOBt (0.184 g; 1.36 mmol) and EDCI (0.261 g; 1.36 mmol) as starting materials. Purification was done by EtOH trituration. 1H-NMR (400 MHz; d6-DMSO): δ 0.90 (t, 3H), 1.42-1.67 (m, 2H), 2.51 (s, 3H), 4.19-4.42 (m, 3H), 6.91 (d, 1H), 7.32 (s, 1H), 7.79 (d, 1H), 7.85-8.07 (m, 3H), 8.38 (d, 1H), 14.14 (s, 1H).
