Triethylamine → 4-(1-Monofluoro-2-decyloxycarbonyl)phenyl 4-octyloxybenzoate

Participants

Reaction Steps

To a solution of the 1-monofluoro-2-decyl 4-hydroxybenzoate prepared in (1) (0.1 g) and triethylamine (0.04 g) in methylene chloride (10 ml) was slowly added under ice cooling a solution of 4-n-octyloxybenzoic acid chloride (0.1 g) in methylene chloride (10 ml). The mixture was left to stand until it reached room temperature and stirred overnight. The mixture was poured in water and extracted with methylene chloride. The extracted layer was washed with dilute aqueous hydrochloric acid solution, water, 1N aqueous sodium carbonate solution and water, in this order, and dehydrated over anhydrous magnesium sulfate. After the solution was distilled under reduced pressure to remove the solvent, the product was purified by silica-gel column chromatography to obtain the titled compound (0.13 g).
