Reaction Steps

To a solution of 4-bromo-3-methyl-2-nitro-phenol (30 g, 0.13 mol) in acetone (200 mL) was added K2CO3 (39 g, 0.28 mol) and iodomethane (17.6 mL, 0.28 mol). The mixture was stirred for 18 hrs and then it was concentrated, diluted with water and extracted with CH2Cl2. The organic phase was dried over Na2SO4, filtered and concentrated to give 1-bromo-4-methoxy-2-methyl-3-nitro-benzene (31 g, 96%) which was used without further purification.
