Hydrochloric Acid → HCID 59478050, compound

Participants

Reaction Steps

To a solution of 4-cyano-1H-pyrrole-3-carboxylic acid (0.034 g), methylamine hydrochloride (0.034 g), triethylamine (0.084 g) and 1-hydroxybenzotriazole (0.034 g) in tetrahydrofuran (2.5 mL) was added N-ethyl—N′-3-dimethylaminopropylcarbodiimide (0.058 g) at room temperature, and this mixture was stirred at same temperature overnight. This reaction mixture was poured into 1 mol/L hydrochloric acid, and this mixture was extracted with ethyl acetate. This organic layer was washed with a saturated aqueous sodium bicarbonate solution and brine, and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: ethyl acetate/n-hexane) to give the title compound (0.035 g).
