Reaction Steps
40% Diethyl azodicarboxylate-toluene solution (9.54 mL) was added to a tetrahydrofuran (40 mL) solution containing 4-bromophenol (2.0 g), methyl hydroxypivalate (2.77 g) and triphenylphosphine (5.49 g), and the mixture was stirred at 70° C. for 3 hours. The reaction mixture was concentrated under reduced pressure, and purified by silica gel column chromatography (n-hexane:ethyl acetate=90:10) to obtain methyl 3-(4-bromophenoxy)-2,2-dimethylpropanoate (3.2 g).
