Reaction Steps
A solution of 0.5 g of benzyl mercaptan in 10 ml of dry dimethylformamide was treated with 60 mg of a 80% dispersion of sodium hydride in mineral oil. After the effervescence had ceased a solution of 1.64 g of 2'-deoxy-5-ethyl-5'-O-(p-toluenesulphonyl)uridine in 20 ml of dry dimethylformamide was added. The mixture was stirred and heated at 100° C. under a nitrogen gas atmosphere. The course of the reaction was followed by thin layer chromatography. After 4 hours the mixture was evaporated to give an oily residue. This was purified by flash column chromatography on silica gel using methanol/dichloromethane (1:9) for the elution. The fractions containing the product were combined and evaporated to yield an oil which solidified and was recrystallized from diethyl ether to give 1.46 g of 5'-benzylthio-2',5'-dideoxy-5-ethyluridine, mp 149°-151° C.
