Reaction Steps

After adding 70% mCPBA (25 g) to a solution of 5-bromo-3-(tert-butyl)-2-(methoxymethoxy)benzaldehyde (30 g, 97 mmol) in methylene chloride (200 ml), the mixture was stirred at 50° C. for 2 hours. The organic layer was washed with a saturated sodium thiosulfate solution and saturated sodium hydrogencarbonate solution and then dried over anhydrous magnesium sulfate. After distilling off the solvent under reduced pressure, the residue was purified by silica gel column chromatography (solvent: n-hexane-ethyl acetate) to yield the title compound (17 g) as a light yellow oil.
