Morpholine → HCID 66638735, compound

Participants

Reaction Steps

Subsequently, 5-(4-chloro-butyrylamino)-2-nitro-benzoic acid methyl ester (50 mg) was dissolved in N,N-dimethylformamide (5 ml). Morpholine (70 mg) and potassium carbonate (44 mg) were added to the solution at room temperature, and the mixture was stirred at room temperature for 3 hr. After the completion of the reaction, distilled water was added thereto at room temperature, and the mixture was subjected to separatory extraction with chloroform. The organic layer was washed with saturated brine, was dried over sodium sulfate, and was then concentrated under the reduced pressure. The residue was purified by column chromatography eluted with a chloroform-methanol system to give 2-nitro-5-(2-oxo-pyrrolidin-1-yl)-benzoic acid methyl ester (45 mg, yield 100%).
