Hydrochloric Acid → 1,1,1Trifluoro-2-octyl 4-(2-fluoro-4-decyloxyphenyloxycarbonyl)biphenyl-4'-carboxylate

Participants

Reaction Steps

Into methylene chloride (20 ml) were added 4,4'-biphenyldicarboxylic acid chloride (0.5 g), (R)-(+)-1,1,1-trifluoro-2-octanol (0.15 g), triethylamine (0.09 g) and dimethylaminopyridine (0.03 g) and the mixture was left to stand for 8 hours in order to allow a reaction to proceed. Thereto were added 2-fluoro-4-decyloxyphenol (0.22 g) and triethylamine (0.09 g), and the mixture was left to stand for 8 hours in order to allow a reaction to proceed. The product was made acidic with 1N hydrochloric acid and extracted with methylene chloride. The extracted layer was washed with 1N aqueous sodium carbonate solution, water, aqueous sodium chloride solution (saturated) and water, in this order, until it was neutralized. After the product was dried over anhydrous magnesium sulfate, it was distilled under reduced pressure to remove the solvent. A solid product thus obtained was purified by silica-gel column chromatography until the titled compound (0.48 g) was obtained.
