Reaction Steps
A solution of phenacylbromide (5.21 g, 26.1 mmol) in toluene (16 mL) was added over 15 minutes to a boiling, stirred solution of 1-(3,4-dihydro-2-naphthyl)pyrrolidine (5.21 g, 26.2 mmol) in toluene (17 mL). The reaction was refluxed 3 hours, diluted with water (15 mL) and refluxed for 4 hours then cooled. The layers were separated and the aqueous phase was extracted with toluene and dried over MgSO4 and concentrated. The material was purified by MPLC using a gradient from 0 to 20% ethyl acetate/hexanes to afford 4.85 g (70% yield) title product as a yellow oil.
