실험 절차

A solution of 2-carboxymethyl-4-methyl-1H-pyrrole-3-carboxylic acid ethyl ester (3.717 g, 17.62 mmol) in dichloromethane (91 ml) in an ice-water bath was added with 4-aminomethyl-1-methyl-piperidin-4-ol (4 g, 19.38 mmol), N,N′-dimethylformamide (9.1 ml), N-ethyl-N′-(dimethylaminopropyl)-carbodiimide hydrochloride (8.751 g, 45.6 mmol) and 1-hydroxybenzotriazol (3,577 g, 26.5 mmol). Upon completion of the addition, the resulting mixture was stirred at room temperature overnight. The mixture was added with ice to quench the reaction, and washed with saturated potassium carbonate solution (10 ml×3) with brine (50 ml×3) The resulting mixture was partitioned and the organic phase was dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure to give 2-{[(4-hydroxy-1-methyl-piperidin-4-ylmethyl)-carbamoyl]-methyl}-4-methyl-1H-pyrrole-3-carboxylic acid ethyl ester (8.891 g) as a brown oil, which was used as such.
