1-Methyl-9-fluorenecarboxylic acid → 1-Methyl-9-fluorenemethanol

Participants

Reaction Steps

A solution of 1-methyl-9-fluorenecarboxylic acid (4.0 g, 17.9 mmol) in 100 mL of THF was charged with IM THF solution of BH3 -THF complex (35 mL, 35 mmol) at 0° C. The reaction mixture was stirred overnight at room temperature then quenched with water (20 mL). The organic layer was washed with 10% potassium carbonate solution, water, brine, dried and evaporated to afford 1-methyl-9-fluorenemethanol (3.2 g, 84.9%).
