Reaction Steps
2-Bromo-3-nitroanisole 2b3 (1.00 g; 4.31 mmol) was dissolved in glacial acetic acid (11.0 mL)/ethanol (11.0 mL) and to the solution was added iron powder (0.98 g; 17.5 mmol). The mixture was stirred at reflux for 3.5 hr and worked up. The reaction mixture was diluted with water (35 mL), neutralized with solid Na2CO3 and the product extracted with CH2Cl2(3×50 m L). The extracts were dried (Na2SO4), filtered and concentrated in vacuo to afford the crude product, 2-bromo-3 methoxyaniline 2b4 (91%; 0.79 g) as a pale yellow oil. MS 201.8 (MH)+; Homogeneity by HPLC (TFA) @ 220 nm: 95%
