Benzylamine (16.0 mL, 145.2 mmol) is dissolved in chloroform (110 mL), and the solution is cooled to 0° C. To this solution is added 4-methoxybenzenesulfonyl chloride (10.0 g, 48.4 mmol). The reaction is stirred at room temperature for 1 hour, and then refluxed for 1 hour. After cooling back to room temperature, the reaction is washed three times with 4N hydrochloric acid (200 mL), twice with water (100 mL), once with brine (50 mL), then dried (Na2SO4), and the solvent is evaporated to give N-[4-methoxybenzenesulfonyl]-benzylamine.
