Reaction Steps

To a solution of 2-bromo-4,6-di-t-butylphenol (Compound D 2.54 g, 8.88 mmol) and catalytic amount of Bu4NI in 20 ml of dry CH2Cl2 at 0° C. was added diisopropylethylamine (9.51 ml, 53 mmol), followed by methoxymethyl chloride (2.02 ml, 26.6 mmol). The reaction mixture was heated to 45° C. for 12 hours. The reaction mixture was then washed with 10% citric acid, then NaHCO3 (sat.), brine, and dried over MgSO4. After filtration and removal of the solvent under reduced pressure, the residue was purified by column chromatography (pure hexane) to yield the title compound (2.79 g) as a colorless oil. 1H NMR δ 7.40 (d, J=2.44 Hz, 1H), 7.30 (d, J=2.4 Hz, 1H), 5.22 (s, 2H), 3.70 (s, 3H), 1.43 (s, 9H), 1.29 (s, 9H).
