실험 절차

358 mg of t-butyl(4-(2,2-dimethyl-[1,3]dioxolan-4-ylmethyl)-5-methoxy-2-nitrobenzyloxy)dimethylsilane was dissolved in 10 ml of tetrahydrofuran. While cooling on ice, 1 ml of a tetrahydrofuran solution containing 1.0 M tetrabutyl ammonium fluoride was added to the reaction solution, and the obtained mixture was then stirred at room temperature for 3 hours. Thereafter, the reaction solution was diluted with ethyl acetate and then washed with a saturated sodium chloride aqueous solution. The organic layer was dried over magnesium sulfate and then concentrated under a reduced pressure. The residue was purified by silica gel column chromatography (hexane-ethyl acetate), so as to obtain 253 mg of (4-(2,2-dimethyl-[1,3]dioxolan-4-ylmethyl)-5-methoxy-2-nitrophenyl)methanol.
