Participants

Reaction Steps

A mixture of 5-benzyloxy-2-nitrophenylacetic acid (4.0 g) and conc. sulphuric acid (0.6 ml) in isopropyl alcohol (40 ml) was stirred under reflux for 1 day. After removal of solvent by evaporation, the resulting residue was dissolved with ethyl acetate. The ethyl acetate extract was washed successively with aqueous sodium hydrogen carbonate solution, water, and brine, and was dried over magnesium sulfate, and concentrated under reduced pressure to give isopropyl 5-benzyloxy-2-nitrophenylacetate (4.20 g).
