18.0 g of 6-hydroxy-2-methylbenzoxazole synthesized from Synthesis 1, 36.6 g of 1-bromohexadecane, 24.0 g of potassium carbonate and 120 ml of N,N-dimethylformamide were mixed with stirring at 90° C. for 4.5 horus. Solids were removed from the reacting solution, and the filtrate was poured into 500 ml of methanol. The separated crystals were separated by filtration to obtain 45.0 g of 6-hexadecyloxy-2-methylbenzoxazole.
