Reaction Steps

50 ml of chloroform and 1.9 ml (0.014 mol) of triethylamine were added and dissolved in 5.3 g (0.011 mol) of 5-(3-hexadecyloxyphenyl)-3-hydroxy-1-phenylpyrazole and stirred at 25° C. To this was dropwise added 2.3 g (0.012 mol) of 2-ethylhexyl chlorocarbonate. After stirring for 30 minutes, cold water was added to the reaction mixture for liquid separation, and the chloroform layer separated was washed two times with 50 ml of cold water and then dried with Glauber's salt. After the Glauber's salt was filtrated out, the chloroform was distilled out, and the remaining precipitate was purified by column chromatography. The product was oily. Yield: 5.7 g, 82%.
