Reaction Steps
A mixture of 1-bromo-4-iodo-benzene (2.5 g, 8.8 mmol), piperidine-4-yl-methanol (2.0 g, 17.7 mmol), potassium phosphate (3.8 g, 17.7 mmol) and copper (I) iodide (3.8 g, 17.7 mmol) in N,N-dimethyl ethanolamine (8.4 mL) was heated to 55° C. for 48 hours. The mixture was allowed to cool to ambient temperature, water was added and the mixture was extracted with ether 2×. The combined organic extracts were washed with water 3×. The organic extract was dried over magnesium sulfate, filtered and concentrated to a crude residue. The residue was dissolved in methylene chloride and passed through a silica gel pad. The pad was eluted ethyl acetate/heptanes (3:7) to ethyl acetate/heptanes (6:4) and the filtrate was concentrated in vacuo to afford [1-(4-bromo-phenyl)-piperidin-4-yl]-methanol as a white solid. (2.4 g)
