Reaction Steps

Iodomethane (10.0 mL, 0.161 mol) was added to a mixture of 2-bromo-4-(tert-butyl)phenol [Intermediate 1, Step 1] (29.5 g, 0.129 mol) and potassium carbonate (42.7 g, 0.309 mol) in dry acetone (400 mL) and the reaction mixture refluxed under nitrogen for 22 hours. The cooled reaction mixture was then concentrated and the residue partitioned between ethyl acetate (400 mL) and 0.3 M aqueous sodium hydroxide solution (300 mL). The organic phase was separated, washed with water (300 mL) and saturated brine (300 mL), dried (MgSO4), filtered and concentrated under reduced pressure to give 2-bromo-4-(tert-butyl)-1-methoxybenzene (32.09 g, 100% yield) as a light yellow oil.
