Reaktionsschritte
To a solution of 5.50 g (23.5 mmoles) of 3,5-di-t-butylbenzoic acid in 25 ml of dry dimethylformamide was added 5.01 g (35.3 mmoles) of iodomethane, and then 6.49 g of anhydrous potassium carbonate. After stirring at room temperature for 2 hours, water was added, the mixture was extracted three times with diethyl ether, the combined organic extracts were washed with brine, dried over sodium sulfate, filtered, and evaporated to give 5.68 g of the title compound as a crystalline solid, m.p. 52.0°-52.5° C. The structural assignment was supported by 1H NMR.
