Reaction Steps

To 6-fluoro-1-methyl-2-tetralone (7.06 g; 39.6 mmol) in a round bottomed flask was added p-toluenesulfonic acid (1.23 g; 6.5 mmol) and the mixture was stirred at room temperature under nitrogen for 15 minutes. Acrylamide (5.62 g; 79.2 mmol) was added and the reaction mixture was heated to 88°-90° C. under nitrogen for three days. The mixture was diluted with ethyl acetate and water and stirred at room temperature for 1 hour. The resulting layers were separated. The organic layer was washed three times with water, dried over MgSO4 and concentrated to a viscous oil. The crude product was crystallized from ethyl acetate to afford 1.59 g (17% yield) of the subtitle compound. Melting point 202° C.
