Morpholine → HCID 23117179, compound

Participants

Reaction Steps

30 μl of triethylamine, 30 μl of morpholine, 45 mg of WSC.HCl and 30 mg of HOBt were added to 2 ml of a THF solution of 52 mg of 1-{3-chloro-5-[(4-(4-chlorothiophen-2-yl)-5-{[(3-methoxypropyl)(methyl)amino]methyl}thiazol-2-yl)carbamoyl]-2-pyridyl}piperidine-4-carboxylic acid hydrochloride, and the mixture was stirred overnight at room temperature. Chloroform was added to the reaction solution. The organic layer was washed with a saturated sodium hydrogencarbonate aqueous solution, with water and with brine, and then dried over sodium sulfate. After the solvent was distilled off, the residue was purified by silica gel column chromatography (eluent: chloroform:MeOH=100:1 to 50:1, hexane:EtOAc=2:1, then chloroform:MeOH=20:1), and suspended in 2 ml of diethyl ether. 2 ml of 4M HCl-EtOAc was added, and the precipitate was collected by filtration to obtain 25 mg of 5-chloro-N-(4-(4-chlorothiophen-2-yl)-5-{[(3-methoxypropyl)(methyl)amino]methyl}thiazol-2-yl)-6-[4-(morpholinocarbonyl)piperidino]nicotinamide hydrochloride.
