Triethylamine → HCID 140504888, compound

Participants

Reaction Steps

To 120 mg pyrrolyl acetic acid from Step 4 was added 97 mg (0.6 mmol, 5 equiv.) of carbonyldiimidazole and 2 mL CH2Cl2. The reaction was mixed at room temperature for one hour, upon which time was added 88 mg (5 equiv.) 1H-pyrazole-1-carboxamidine hydrochloride, 0.16 mL (10 equiv.) triethylamine, and a catalytic amount of 4-dimethylaminopyridine. The reaction was mixed at room temperature for one hour, filtered to remove any precipitates formed, and washed with water. The organic phase was separated from the aqueous phase and concentrated to afford 59 mg crude N-ethyl-4-(1-{[(imino-pyrazol-1-yl-methyl)-carbamoyl]-methyl}-5-phenyl-1H-pyrrol-2-yl)-benzamide, which was used in the next step without purification.
