Reaktionsschritte

To a saturated solution of NH3 in CH3OH (50 mL) was added 5-bromo-2-bromomethyl-benzoic acid methyl ester (4.8 g, 16 mmol). The reaction mixture was stirred in a sealed tube at 40° C. overnight. The mixture was cooled to room temperature and the resultant white solid was collected to afford 6-bromoisoindolin-1-one (2.2 g, 67%). 1H NMR (400 MHz, DMSO) δ 8.71 (s, 1H), 7.75 (d, 2H), 7.53 (s, 1H), 4.32 (s, 2H).
