Hydrochloric Acid → 4-(3,3,4,4,4-Pentafluorobutyl)benzenemethanol

Participants

Reaction Steps

4-(3,3,4,4,4-Pentafluorobutyl)benzenemethanol acetate (525 mg, 1.42 mmol) was heated to reflux with aqueous potassium hydroxide solution (40%; 399 μL, 2.84 mmol) in methanol (6 mL) for two hours. The residue was acidified with 1 M aqueous hydrochloric acid, and extracted with ethyl acetate. The combined organic layers were concentrated under reduced pressure. Flash chromatography gave 314 mg of 4-(3,3,4,4,4-pentafluorobutyl)benzenemethanol; 1H NMR (300 MHz, CDCl3) δ 7.33 (d, 2H), 7.21 (d, 2H), 4.68 (dbr, 2H), 2.91 (m, 2H), 2.32 (m, 2H), 1.71 (tbr, 1H) ppm.
