Sodium Carbonate → 2-Chloro-3-methoxyaniline

Participants

Reaction Steps

2-Chloro-3-nitroanisole C3 (1.38 g; 7.36 mmol) was dissolved in a mixture of glacial acetic acid (19 mL)/ethanol (19 mL). To this solution was added iron powder (1.64 g; 29.4 mmol). The mixture was stirred at reflux for 3.5 hr and worked up. The reaction mixture was diluted with water (70 mL), neutralized with solid Na2CO3 and the product extracted with CH2Cl2(3×150 mL). The extracts were combined and washed with saturated. brine and then dried over (Na2SO4), filtered and concentrated in vacuo to afford the crude product, 2-chloro-3-methoxyaniline C4 (100%; 1.2 g) as a yellow oil. This material was used as such in the following steps.
