Reaction Steps

33.4 g of (±)-2-azabicyclo[2.2.1]hept-5-en-3-one were dissolved in acetonitrile (240 ml) and pyridine (48.3 ml) under nitrogen. At 12° C., 68.6 g of phenylacetyl chloride were added dropwise over the course of 30 minutes. The mixture was then stirred at room temperature for 3.5 hours. 240 ml of water were added to the mixture. The acetonitrile was evaporated off in vacuo, and the aqueous phase was extracted 3 times with ethyl acetate (150 ml). The combined org. phases were washed with 1N HCl (150 ml), saturated NaCl (150 ml) and water (150 ml), dried with magnesium sulphate and completely evaporated. The crude product was filtered through silica gel (hexane:ethyl acetate=1:1). 68.34 g of the crude product were obtained as a yellow oil.
