4-Toluenesulfonyl chloride → HCID 13057119, compound

Participants

Reaction Steps

1-(2-Hydroxyethoxy)methyl-5-fluorouracil (1 g) obtained in Example 1 was dissolved in pyridine (5 ml) and to the solution was added p-toluenesulfonylchloride (1.12 g) under cooling in an ice bath, and then the mixture was stirred at room temperature for 1.5 hours. After completion of the reaction, the mixture was poured into ice-water and the resulting oil was extracted with chloroform (30 ml). The chloroform layer was washed with hydrochloric acid and then with water, and dried over magnesium sulfate to give crystalline 1-(2-p-toluenesulfonyloxyethoxy)methyl-5-fluorouracil (1.2 g).
