Hydrochloric Acid → Methyl 2-(4-(2-oxopropyl)phenoxy)acetate

Participants

Reaction Steps

Sodium metabisulphite (26 g) in water (60 ml) was added to 1-(4-carbomethoxymethoxyphenyl)propan-2-one oxime (7.5 g) in methanol (50 ml) and the mixture refluxed for 6 hours. The reaction mixture was cooled, concentrated hydrochloric acid (30 ml) added and the mixture extracted with ethyl acetate. The combined ethyl acetate extracts were washed with water followed by sodium bicarbonate solution. The ethyl acetate layer was dried (MgSO4) and evaporated to give the title compound as an oil which crystallised on standing, (mp 63°-70°l ). τ (CDCl3) 7.91 (3H, s), 6.30 (2H, s), 6.26 (3H, s), 5.42 (2H, s), 3.17 (2H, d, J=8 Hz), 2.87 (2H, d, J=8 Hz).
