Versuchsvorschrift

To a solution of commercially available 1-(2-bromophenyl)methanamine hydrochloride salt (1 eq.) in CH2Cl2 (0.3M) at room temperature was added triethylamine (2.1 eq) then acetic anhydride (1.1 eq.). The mixture was stirred at room temperature for 6 h, poured in aqueous HCl (0.5N) and extracted with CH2Cl2. The organic extract was dried over MgSO4 filtered and concentrated to afford the desired compound as a white solid.
