Versuchsvorschrift

500 g (1.78 mol) of 2-(4-Bromo-phenyl)ethylamine hydrobromide, 1 liter (12.4 mol) of ethyl formate and 248 mL (1.78 mol) of triethylamine were combined and heated to reflux for 3 hrs. The reaction was treated with 1 liter each of deionized water and ethyl acetate. The organic layer was separated and washed with 1 liter each of water and brine. The organic layer was dried over anhydrous magnesium sulfate, filtered and concentrated to yield 378 g of a solid.
