Procedure
A solution of (E)-3-(5-bromo-2-methoxy-phenyl)-acrylic acid (0.072 g, 0.28 mmol) in DMF (10 ml) is treated with 2-(1H benzotriazol-1-yl)-1,1,3,3,-tetramethyluronium tetrafluoroborate (0.09 g, 0.28 mmol) and diisopropylethylamine (0.058 ml, 0.33 mmol). The resultant solution is added to 2-[4-(4-fluoro-benzyl)-piperidin-1-yl]-ethylamine and the mixture stirred at RT for 18 hours. The solvents are evaporated and the crude residue purified by preparative HPLC to afford (E)-3-(5-bromo-2-methoxy-phenyl)-N-{2-[4-(4-fluoro-benzyl)-piperidin-1-yl]-ethyl}-acrylamide [MH]+ 475.2
