2-methoxyfluoren-9-one → 2-Methoxy-9H-fluoren-9-ol

Participants

Reaction Steps

A solution of 2-methoxy-9-fluorenon (6 g, 28.5 mmol) in 30 mL of THF was charged with 1M THF solution of BH3 -THF complex (60 mL, 60 mmol) at 0° C. The reaction mixture was stirred for 6 hr at room temperature, then quenched with water (100 mL). The resulting precipitate was filtered off, washed with water and dried to afford 5.6 g (93.3%) of pure 2-methoxy-9-fluorenol.
