Reaction Steps
4.0 g of 3,5-di-tert.-butyl-2-hydroxybenzaldehyde (CAS # 37942-07-7) was dissolved in dimethylformamide (DMF). This was treated with 0.89 g of sodium hydride (50% in oil suspension) and stirred at 25° C. until hydrogen was no longer evolved. To this was added 2.01 ml n-bromobutane and the mixture was heated to 85° C. for 14 hr. This was cooled and poured into water. The aqueous was extracted with ether. The ether layer was washed with water, dried (MgSO4), and solvent was removed. Purification was accomplished by florsil column chromatography (15% ether/hexane) to give 5.4 g of 3,5-di-tert.-butyl-2-butyloxybenzaldehyde; 1H NMR (CDCl3) δ 10.31 (s, 1H,aldehyde), 7.70 (dd,4H,aromatics), 3.94 (t,2H,—OCH2—).
