실험 절차
6.9 g of the benzoxazole derivative obtained in Step (c) above was dissolved in 50 ml of dimethylformamide and the solution was stirred at 80° to 90° C. for 6 hours together with 8 g of anhydrous potassium carbonate and 11 g of hexadecyl bromide. After the completion of the reaction, the insoluble material was removed by filtration. To the filtrate was added 150 ml of methanol and the mixture was cooled with ice to precipitate crystals. The crystals were collected by filtration, thus obtained 8.8 g (62%) yield) of 6-tert-butyl-5-hexadecyloxy-2-methylbenzoxazole.
