Ethyl Acetate → 5-Hydroxy-4-(2-methoxyethoxy)-2-nitrobenzonitrile

Participants

Reaction Steps

To a solution of 5-methoxy-4-(2-methoxyethoxy)-2-nitrobenzonitrile (1.5 g) in anhydrous DCM (30 mL) was added anhydrous AlCl3 (6 g) at 0° C. The resulting mixture was heated to reflux for 1 h. After reaction finished, the mixture was diluted with 1N aqueous HCl (50 mL) and exacted with EA (3×50 mL). The combined organic layer was dried over Na2SO4, concentrated under reduced pressure, and purification by silica chromatography to give 0.5 g of 5-hydroxy-4-(2-methoxyethoxy)-2-nitrobenzonitrile. 1H-NMR (400 MHz, CDCl3): δ: 7.85 (s, 1H), 7.33 (s, 1H), 4.32-4.30 (m, 2H), 3.87-3.84 (m, 2H), 3.50 (s, 3H).
