37.3 g (0.1 mol) of 2-methyl-6-hexadecyloxybenzoxazole obtained by the reaction of 2-methyl-6-hydroxybenzoxazole with hexadecyl bromide was added to a mixture composed of 30 ml of hydrochloric acid and 300 ml of ethanol and the mixture was stirred at a temperature range between 40° C. and 50° C. for 1 hour. After cooling, the crystals deposited were collected by filtration and washed with ethanol to obtain 35.8 g of 2-acetylamino-5-hexadecyloxyphenol.
