Reaction Steps
I-PrNEt2 (834 g, 6.46 g) and chloromethyl methyl ether (451 g, 5.60 mol) were gradually added to a solution of the 5-bromo-3-(tert-butyl)-2-hydroxybenzaldehyde (1333 g, 4.67 mol) in methylene chloride (4000 ml) while cooling on ice, and the mixture was stirred at room temperature for 2 days. After first distilling off the solvent under reduced pressure, ethyl acetate was added to the residue, washing was performed twice with brine, the organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (solvent: n-hexane-ethyl acetate) to yield the title compound (1338 g) as a light yellow oil.
