Triethylamine → HCID 12802104, compound

Participants

Reaction Steps

2.0 Grams of 2'-deoxy-3',5'-di-O-propionyl-5-fluorouridine are dissolved in 25 ml of dry dioxane and the solution is ice cooled. 2 Milliliters of triethylamine and 1.7 g of 2-methylbenzoyl chloride are added to the solution and the mixture is subjected to reaction at room temperature for 15 minutes and then at 70° C. for 30 minutes. The reaction liquid is cooled and triethylamine hydrochloride is filtered off. The filtrate is concentrated under reduced pressure and the oily residue is purified by column chromatography on silica gel (elution solvent: chloroform). The The purified oily substance is dissolved in about 15 ml of dimethyl sulfoxide and the solution is added dropwise to about 400 ml of ice water under vigorous agitation whereupon a precipitate is formed. The resultant precipitate is collected by filtration, washed with water and dried at room temperature under reduced pressure whereby 1.5 g (yield: 56.4%) of powdery 3-(2-methylbenzoyl)-2'-deoxy-3',5'-di-O-propionyl-5-fluorouridine are obtained.
