Reaktionsschritte

A solution of methyl 4-chloro-3-nitrobenzoate (10 g) dissolved in acetic acid (100 mL) was treated with Iron powder (10.36 g) under nitrogen. The resulting mixture was stirred vigorously at 20° C. for 2 h. The reaction mixture was filtered through celite and the filtrate evaporated to dryness to afford crude product. The residue was diluted with aqueous sodium bicarbonate solution (200 mL), and extracted with dichloromethane (250 mL). The organic layer was separated, dried (MgSO4), filtered and evaporated to afford the sub title compound (8.41 g).
