실험 절차
A solution of 2,7-dimethyl-9-fluorenecarboxylic acid (4.3 g, 18.0 mmol) in THF (100 mL) was charged with 1M THF solution of BH3 -THF complex (36.0 mL, 36.0 mmol) at 0° C. The reaction mixture was stirred overnight at room temperature then quenched with water (100 mL) and HCl (3 mL). After addition of ethyl acetate (50 mL) the organic layer was separated and washed with 10% potassium carbonate solution, water, brine, dried over magnesium sulfate and evaporated to afford 2,7-dimethyl-9-fluorenemethanol (3.0 g, 74.4%).
