Sodium Iodide → HCID 19772580, compound

Participants

Reaction Steps

A mixture of 4-methoxycarbonyl-4-(N'-phenylpropionamido)piperidine (7.34 g, 25 mmol), 2-bromoethanol (3.96 g, 32 mmol), sodium carbonate (20.0 g, 189 mmol), and sodium iodide (1.0 g) in acetonitrile (200 ml) was heated to reflux for three days. The reaction mixture was cooled and filtered. The filtrate was concentrated under vacuum yielding an oily residue. The residue was chromatographed on silica gel (250 g; ethyl acetate/hexane; 1:4) to yield 1-(2-hydroxyethyl)-4-methoxycarbonyl-4-(N'-phenylpropionamido)piperidine (8.1 g, 96%) as an oil.
