1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → 4-((S)-2-cyclopropylaminomethyl-pyrrolidine-1-carbonyl)-3,5-dimethyl-1H-pyrrole-2-carbaldehyde

참여 물질

반응 단계

A mixture of 5-formyl-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (270 mg, 1.61 mmol), cyclopropyl-(S)-1-pyrrolidin-2-ylmethyl-amine (220 mg, 1.57 mmol), HOBt (199 mg, 1.47 mmol), EDAC (344 mg, 1.8 mmol) and TEA (0.5 mL) in DMF (7 mL) was stirred at rt for 48 hours. The reaction was concentrated, diluted with sodium bicarbonate and extracted with DCM. The combined DCM was dried, concentrated and filtered through silica gel to give 4-((S)-2-cyclopropylaminomethyl-pyrrolidine-1-carbonyl)-3,5-dimethyl-1H-pyrrole-2-carbaldehyde.
