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 (200ml) 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.
