4-Methylmorpholine → HCID 12136647, compound

Participants

Reaction Steps

N,N-Dimethylformamide (8.4 ml) was added to a mixture of 2-(1-adamantyl)-N-propylethylamine (Intermediate No. 1-6) (0.37 g, 1.7 mmol) and 5-(4-pyridyl)valeric acid (Intermediate No. 5-1) (0.30 g, 1.7 mmol), and the whole was stirred at room temperature. N-Methylmorpholine (0.27 ml, 2.5 mmol) and then 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.38 g, 2.0 mmol) were added thereto, and the whole was stirred overnight. The reaction mixture was concentrated under reduced pressure, ethyl acetate (20 ml) was added to the residue, and the whole was washed with a saturated aqueous sodium hydrogencarbonate solution (20 ml) and saturated brine (5 ml) successively. The organic layer was dried over sodium sulfate, and ethyl acetate was evaporated under reduced pressure. The residue was purified by basic silica gel column chromatography to give 0.21 g (33%) of the titled compound as a colorless oily matter.
