Reaktionsschritte

3-(3-bromo-2,5-dichlorophenoxy)-4-chloro-2-nitroaniline (2.68 g, 6.50 mmol) and tin(II) chloride dihydrate (7.33 g, 32.5 mmol) were suspended in MeOH (50 mL) and heated to 75° C. under a reflux condenser and N2. After 11 hours, the reaction mixture was allowed to cool to room temperature, and concentrated under reduced pressure. The resulting residue was diluted with ethyl acetate (150 mL), after which 10% aqueous sodium carbonate (250 mL) was added with vigorous stirring until the pH was 10. The resulting suspension was filtered through celite, the filtrate was extracted with ethyl acetate. The combined organic fractions were dried (MgSO4), filtered and the solvent was evaporated under reduced pressure to yield the title compound. LRMS (M+1)=382.5.
