Procedure

4-Nitrophenol (5 g), methyl 2-bromoisobutyrate (5.6 mL) and K2CO3 (7.5 g) were suspended in acetone (60 mL). The yellow solution was refluxed overnight. The reaction mixture was diluted with water (150 mL) and extracted with ethyl acetate (2×100 mL). The organic layers were evaporated to give methyl 2-(4-nitrophenoxy)isobutyrate.
