1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 178480472, compound

Participants

Reaction Steps

A mixture of 4-(2,6-difluoro-benzoylamino)-1H-pyrazole-3-carboxylic acid (134 mg, 0.50 mmol), 4-amino-N-methylpiperidine (50.0 μl, 0.45 mmol), EDAC (104 mg, 0.54 mmol) and HOBt (73.0 mg, 0.54 mmol) in DMF (3 ml) was stirred at ambient temperature for 16 hours. The mixture was reduced in vacuo, the residue taken up in EtOAc and washed successively with saturated aqueous sodium bicarbonate, water and brine. The organic portion was dried (MgSO4) and reduced in vacuo to give 4-(2,6-difluoro-benzoylamino)-1H-pyrazole-3-carboxylic acid (1-methyl-piperidin-4-yl)-amide as a white solid (113 mg, 69%). (LC/MS: Rt 2.52, [M+H]+ 364.19).
