Procedure
A 20% solution of piperidine in dry dimethylformamide (5 ml) was added to 2',3'-dideoxy-5-ethynyl-5'-O-(N-fluorenylmethoxycarbonyl-L-isoleucinyl)-3'-fluorouridine (0.57 g, 0.96 mmol) and after 4 minutes at room temperature, the solvents were evaporated rapidly under high vacuum with minimal heating. Trituration of the residue with several portions of ether afforded a crop of the title compound containing ~5% of N,N'-dicyclohexylurea.
