실험 절차

A stirred solution of 2-carboxymethyl-4-methyl-1H-pyrrole-3-carboxylic acid ethyl ester (2.67 g, 12.67 mmol) in N,N-dimethylformamide (7 ml) and dichloromethane (65 ml) was added with 2-morpholin-4-yl-ethamine (1.81 g, 13.9 mmol), N-ethyl-N′-(dimethylaminopropyl)-carbodiimide hydrochloride (4.84 g, 25.34 mmol) and 1-hydroxybenzotriazol (1.71 g, 12.67 mmol) in an ice/water-bath. Upon completion of the addition, the reaction mixture was stirred at room temperature overnight, added with cold water (50 ml) and extracted with dichloromethane (50 ml×3). The combined organic extracts were washed with saturated sodium bicarbonate (50 ml), water (50 ml), brine (50 ml), dried with anhydrous sodium sulfate, filtered and concentrated under reduced pressure to give 4-methyl-2-[(2-morpholin-4-yl-ethylcarbamoyl)-methyl]-1H-pyrrole-3-carboxylic acid ethyl ester (3.48 g, 85%) as a brown oil which was used as such.
