Versuchsvorschrift
To 3-bromo-5-methoxycarbonyl-benzoic acid (3 g, 11.6 mmol, 1 eq) was added SOCl2 (20 mL) and the reaction heated at reflux overnight. The excess SOCl2 was removed in vacuo and the residue obtained was dissolved in THF (15 mL) and added dropwise to a solution of NH3 (38% aqueous, 30 mL). The precipitate that formed was collected by filtration, washed with water and dried to give the title compound as a white solid (2.8 g, 94%).
