Reaction Steps
A mixture of 56.8 g (0.4 mole) kojic acid, 55,3 g (0.4 mole) potassium carbonate, 133.3 g (0.4 mole) 1-octadecyl bromide, 1 g potassium iodide and 450 mL anhydrous dimethylformamide is stirred for 10 hours at 90° C. After cooling, the mixture is mixed with 1.5 L of water, the precipitate formed is filtered off, well stirred up once with ethyl acetate, filtered off and recrystallized from propan-2-ol with the addition of active charcoal. There is obtained a colorless product: m.p. 71°-73° C.
