Participants

Reaction Conditions

Reaction Steps

A mixture of 3-nitrophenol (0.50 g, 3.6 mmole), ethyl bromodimethylacetate (0.64 g, 3.3 mmole), K2CO3 (1.3 g, 9.4 mmole), potassium iodide (catalytic) in absolute ethanol (8 mL) was heated at 70° C. for 18 h. The reaction mixture was cooled, poured into a saturated solution of NaHCO3, and extracted with dichloromethane. The product, ethyl 2-methyl-2-(3-nitrophenoxyl)propanate, was obtained after purification by column chromatography over silica gel. 1H NMR (CDCl3): δ 7.85 (dt, 1H, J=1.2 and 8.1 Hz), 7.68 (t, 1H, J=2.4 Hz), 7.40 (t, 1H, J=8.4 Hz), 7.19-7.13 (m, 1H), 4.26 (q, 2H, J=7.2 Hz), 1.64 (s, 6H), 1.26 (t, 3H, J=7.21),
