Reaction Conditions:
with iron(III) chloride;pyrographite;hydrazine hydrate in methanol for 16 h;Reflux;
Steps:
Intermediate s: 5-Chloro-2-methoxyaniline
Intermediate s: 5-Chloro-2-methoxyaniline Hydrazine hydrate (80%, 186 g, 2.975 mol) was added drop-wise to a refluxing mixture of 4-chloro-1-methoxy-2-nitrobenzene (Intermediate 4, 93 g, 0.496 mol), iron trichloride (9.3 g, 10% wt) and active carbon (9.3 g, 10% wt) in methanol (1 L). After the addition, the reaction mixture was stirred at reflux for 16 h, the reaction mixture was filtered and the solvent evaporated from the filtrate under vacuum. The residue was washed with petroleum ether (2 L) to give 5-chloro-2-methoxyaniline as a white solid (76.7 g, 98%). 1H NMR (300MHz, CDCI3) δ 6.67-6.65 (m, 3H), 3.83 (bs, 2H), 3.81 (s, 3H).
