Sodium Hydroxide → 4-(3-Bromophenyl)butan-1-ol

Participants

Reaction Steps

A cold (0° C.) solution of 4-(3-bromophenyl)butyric acid (2.85 g, 11.7 mmol) in THF was treated slowly with a solution of B2H6-THF (35 mL), stirred at room temperature for 18 hours, poured into ice/water, basified with 2.5 N NaOH to pH=11 and extracted with CH2Cl2. The extracts were combined, washed with brine, dried over MgSO4 and concentrated in vacuo. Purification of the resultant residue by column chromatography using hexanes/CH2Cl2/MeOH (4/4.5/0.5) as the eluting solvent afforded 4-(3-bromophenyl)butan-1-ol as a colorless oil (1.9 g, 70% yield.
