Triethylamine → HCID 23114818, Verbindung

The [6-[(4-chlorophenylsulfonyl) (2,5-difluorophenyl)methyl]pyridin-3-yl]methylamine (30 mg, 0.073 mmol) obtained in Example 351, 3-pyridylacetic acid hydrochloride (16 mg, 0.092 mmol), 4-(dimethylamino)pyridine (5 mg, 0.04 mmol) and triethylamine (0.025 ml, 0.18 mmol) were dissolved in dichloromethane (5 ml). To the resulting solution was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (17 mg, 0.089 mmol). After stirring at room temperature for 14 hours, a saturated aqueous solution (0.1 ml) of sodium bicarbonate was added to the reaction mixture. The residue obtained by concentration of the reaction mixture under reduced pressure was subjected to flash silica gel chromatography. A fraction obtained from the elution portion with dichloromethane:methanol 30:1 was concentrated under reduced pressure, whereby a white solid was obtained. The white solid was washed with ether, whereby the title compound (35 mg, 0.066 mmol, 90%) was obtained as a white powder.
