Yield	Reaction Conditions	Operation in experiment
85.1%	With hydrogen;Raney Ni; In ethyl acetate; for 4.0h;	Step-2: 2-Amino-6-bromo-4-chloro-phenol; To a solution of <strong>[15969-10-5]2-bromo-4-chloro-6-nitro-phenol</strong> (2.7 g, 10.6 mmol) in ethyl acetate was added raney Ni (1 g) and was hydrogenetaed at ballon pressure for 4 hours. The reaction mixture was filtered through celite bed and mother liquor was concentrated to afford 2 g (85.1%) of 2-Amino-6-bromo-4-chloro-phenol. LCMS [M+1]: 224.0. 1H-NMR (400 MHz, DMSO-d6) delta (ppm): 6.67 (s, 1H), 6.61 (s, 1H), 6.57 (s, 1H), 5.2 (bs, 2H).
64%	With iron; ammonium chloride; In ethanol; water; at 90℃; for 1.25h;	Step 2: <strong>[15969-10-5]2-bromo-4-chloro-6-nitrophenol</strong> (1.0 equiv.) was suspended in EtOH (0.5) and then iron powder (8.0 equiv.) followed by Ni l .C (8.0 equiv.) and Water (1/10 of EtOH volume) was added. The mixture was heated at 90 C for 75 min and then filtered hot through ceite. The filtrate was concentrated in vacuo and ther residue dissolved in EtOAc and washed with water and brine. The organic layer was dried (MgSO4), filtered and concentrated in vacuo to give a dark brown residue. This material was suspended in DCM and titurated with heptane. The dark brown suspension was collected by filtration to afford 2- amino-6-bromo-4-chlorophenol in 64% yield. LCMS (m 'z) (M+H) = 223.8, Rt = 1.11 min
