Procedure
2-(3-Bromo-propoxy)-biphenyl (1.0 g) was reacted with morpholine (5 mL) at 50° C. for 1 hour to form 4-[3-(biphenyl-2-yloxy)-propyl]-morpholine. The excess morpholine was evaporated and water was added, followed by extraction with ethyl acetate. Removal of ethyl acetate afforded 900 mg of 4-[3-(biphenyl-2-yloxy)-propyl]-morpholine (t) as an oil which was used without further purification: m/e: 297.17, MS (ES+): 298.2; 1H NMR (500 MHz, CDCl3): 7.8-7.0 (m, 9H), 4.0 (m, 2H), 3.7 (m, 4H), 2.5 (m, 6H) and 1.8 (m, 2H).
