4-Methylmorpholine → HCID 58734275, compound

Participants

Reaction Steps

To a dichloromethane (5 ml) solution of 6-[(4-chlorophenylsulfonyl)(2,5-difluorophenyl)methyl]pyridin-2-ylamine (74 mg, 0.187 mmol) were added N-methylmorpholine (90 μl, 0.818 mmol), 1-hydroxybenzotriazole (11 mg, 0.313 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (60 mg, 0.312 mmol) and 2-pyridylacetic acid hydrochloride (54 mg, 0.312 mmol). The resulting mixture was stirred at room temperature for 24 hours. The reaction mixture was diluted with dichloromethane. The diluted solution was washed sequentially with water, a saturated aqueous solution of sodium bicarbonate and brine. The organic layer thus obtained was dried over magnesium sulfate, and concentrated under reduced pressure. The residue thus obtained was subjected to flash silica gel column chromatography. The fraction obtained from the hexane:ethyl acetate=4:1 eluate was concentrated under reduced pressure to give the title compound (48 mg, 0.0934 mmol, 50%) as a white amorphous substance.
