Potassium Hydroxide → HCID 15754281, compound

Participants

Reaction Steps

4.0 g (0.01 mol) of N-(3,5-dichloro-4-fluoro-α,α-dimethylbenzyl)-N-(2-oxopropyl)phenylacetamide prepared in accordance with the method of Reference Example 8, was dissolved in 50 ml of ethyl alcohol, and 0.5 g (0.009 mol) of potassium hydroxide powder was added thereto. The mixture was refluxed under heating for 10 minutes. Then, the solvent was distilled off under reduced pressure, and water was added thereto and extracted with ethyl acetate. The ethyl acetate layer was dried over an hydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure, followed by purification by silica gal column chromatography (n-hexane/ethyl acetate) to obtain 2.5 g (yield: 67.5%) of the desired compound as colorless crystals.
