5.9 g (18.9 mmol) of 12-bromododecanol, 1.06 g (10 mmol) of sodium carbonate, 4.92 g of (25 mmol) of 3,5-dinitrobenzyl alcohol were dissolved in 50 mL of DMF and heated with stirring at 100° C. for 12 hours (under a nitrogen atmosphere). The reaction solution was poured into ice water to precipitate a solid, and the solid was recrystallized with methanol. Thus, 5.73 g (15 mmol) of 12-(3,5-dinitrobenzyloxy)-dodecanol was prepared. (The yield was 79%.)
