Ethanol hydrochloride → 3-[4-[4-(1,1,1,3,3,3-Hexafluoro-2-hydroxypropan-2-yl)-2-propylphenyloxy]butyl]-1,5,5-trimethylimidazolidine-2,4-dione

Participants

Reaction Steps

Hydrochloric acid-ethanol (2 mol/L, 2 mL) was added to 3-[4-[4-[1,1,1,3,3,3-hexafluoro-2-(methoxymethyl)oxypropan-2-yl]-2-propylphenyloxy]butyl]-1,5,5-trimethylimidazolidine-2,4-dione (55.7 mg, 0.11 mmol), followed by stirring at room temperature for one hour. The reaction solution was concentrated under reduced pressure, and the resulting residue was purified by silica gel preparative thin-layer chromatography (hexane:ethyl acetate=2:1) to obtain 41.8 mg of the title compound (yield: 82%) as a colorless crystalline powder.
