Procedure

A heterogeneous mixture of 4-nitrophenol (5 g), methyl 2-bromoisobutyrate (5.6 mL) and K2CO3 (7.5 g) in acetone (60 mL) was refluxed overnight. The reaction mixture was then 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 (49).
