Reaction Conditions

Reaction Steps

After adding 41.0 g (0.30 mmol) of potassium carbonate and 23.8 g (0.19 mmol) of 2-bromopropane to a solution of 25.0 g (0.15 mol) of 3,5-dihydroxybenzoic acid methyl ester in N,N-dimethylformamide (250 ml), the reaction mixture was stirred at 80° C. for 4 hours. Water was added to the reaction mixture, extraction was performed with acetic acid ethyl ester, and then the organic layer was washed with brine, dried and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane:acetic acid ethyl ester=5:1) to obtain 12.0 g of 5-hydroxy-3-isopropoxybenzoic acid methyl ester (yield: 38%) as a colorless oil.
