Morpholine → HCID 910425, compound

Participants

Reaction Steps

To a DMF solution (10 ml) of 2-methyl-3-nitro-benzoic acid (500 mg) and morpholine (361 mg), WSCI (793 mg), HOBt (560 mg) and N-ethyldiisopropylamine (1.44 ml) were added, followed by stirring at room temperature. To this, water was added, followed by extraction with ethyl acetate, which was subsequently washed with saturated aqueous sodium chloride solution, and the organic layer was dried over sodium sulfate. After the sodium sulfate was filtered off, the solvent was distilled off under reduced pressure, followed by purification by silica gel column chromatography (dichloromethane/methanol=40/1 to 10/1), to obtain the desired compound (587 mg, 85%).
