Versuchsvorschrift

To a solution of 2-hydroxybenzoic acid (110 g, 796 mmol) in MeOH (400 mL) was bubbled HCl (gas) for 1 h. The resulting mixture was stirred at 50° C. overnight. The reaction mixture was cooled to room temperature and concentrated under reduced pressure to give the crude methyl 2-hydroxybenzoate that was used directly without further purification.
