Sodium Hydroxide → 3,5-Dichlorobenzenepropanol

Participants

Reaction Steps

LiAlH4 (1M in Et2O, 10 mL, 10 mmol) wasslowly added to a solution of 3-(3,5-dichlorophenyl)-propionic Acid (2.19 g, 10 mmol) in Et2O (50 mL). The reaction was heated at reflux for 2 h. The reaction was cooled to room temperature and 2N NaOH (1 mL) and aqueous NH4Cl (satd., 3 mL) as carefully added. The solution was filtered through Celite and the filtrate was dried over MgSO4, filtered, and concentrated. The product was purified by flash chromatography (25% EtOAc/hexanes) to afford 3-(3,5-dichlorophenyl)-propanol (640 mg). 1H NMR (400 MHz, CDCl3) δ 7.17 (m, 1H), 7.07 (m, 2H), 3.64 (m, 2H), 2.65 (t, 2H), 1.84 (m, 2H).
