Intermediate Example Int20.014-(4-bromo-3-methoxyphenoxy)-1 -methylpiperidine To a stirred suspension of sodium hydride (1.76 g; 60% w/w sodium hydride in oil) in DMF (55 mL) was added 1 -methylpiperidin-4-ol (3.37 g) at 0 C. The mixture was stirred at room temperature for 30 minutes. 1 -bromo-4-fluoro-2- methoxybenzene (3.0 g) was added and the mixture was stirred at 100 C for 1 h. Water was added and the mixture was extracted with ethyl acetate. The organic phase was washed with saturated sodium chloride solution, dried (sodium sulfate) and the solvent was removed in vacuum. Aminophase-silica- gel chromatography gave 3.65 g of the title compound.
