Procedure

To a solution of 3-nitrophenol (8.35 g, 60 mmol), in DMF (50 ml) was added K2CO3 (16.56 g, 120 mmol) and methyl 1,4-bromobutyrate (11.95 g, 66 mmol). The reaction was stirred at room temperature for 16 h. The reaction was diluted with ethyl acetate and water. The organic phase was separated and washed with water (2×200 ml). The organic phase was dried with Na2SO4 and concentrated in vacuo. The required ether was isolated following chromatography (ethyl acetate:heptane, 1:9) as a pale yellow solid (12.2 g, 85% yield). LCMS purity 100%, m/z 240 [M++H]+.
