Versuchsvorschrift

To a solution of 3-ethylaniline (Aldrich, 4.84 g, 40 mmol) in methanol (10 mL) was added methanesulfonic acid (4.4 g, 45 mmol) at 4° C., then the reaction mixture was stirred at 25° C. for 30 minutes to yield a solution with white precipitates. The precipitates were collected by filtration, washed with ether, and dried under vacuum to afford 7.7 g of 3-ethylaniline mesylate (7.7 g, 91 % yield).
