A solution of 3-(3-methoxyphenyl)-propanol (69 g, 0.42 mole) and pyridine (400 mL) was stirred at 5° C. as p-toluenesulfonyl chloride (87 g, 0.46 mole) was added portionwise. The reaction mixture was stirred at room temperature for 2 hours, then was poured onto ice/concentrated HCl and was extracted with ether. The extracts were washed with 2N HCl, wawter, saturated aqueous NaCl, dried (MgSO4), filtered, and evaporated to yield 126 g yellow oil, (95%); M+ 320.
