Reaction Steps

To a solution of methyl 2,4-dihydroxybenzoate (5.4 g) and 2-iodopropane (10.2 g) in benzene (200 mL) was added Ag2CO3 and the mixture was heated in a 100° C. oil bath for 1 h. Additional methyl 2,4-dihydroxybenzoate (5 g) and 2-iodopropane (5 g) were added and the mixture was heated at 100° C. for another 2 h. After cooling, the mixture was filtered and concentrated. The residue was purified by flash chromatography eluted with 30:1 toluene/EtOAc to give 3 g of the title compound along with 1.2 g of isomer methyl 4-hydroxy-2-isopropoxybenzoate.
