Reaction Steps
A solution of triethylamine (3.9 mL, 28.2 mmol) in dioxane (12 mL) was deareated by bubbling nitrogen through for 15 min. Palladium acetate (0.60 g, 0.26 mmol) and triphenylphosphine (0.183 g, 0.70 mmol) were added and the solution was heated at 70° C. for 20 min to give a dark brown solution. 5-Iodo-3′-deoxyuridine (5.0 g, 14.1 mmol) and methyl 2,4-pentadienoate (2.5 g, 22.3 mmol) was added and the mixture was heated under reflux for 15 h. The solvent and volatile components were evaporated in vacuo and the residue was partitioned between water (15 mL) and EtOAc (15 mL). The phases were separated and the aqueous phase was extracted twice with EtOAc (10 mL each). The combined organic phase was washed with brine and concentrated. The residue was dissolved in MeOH (15 mL) and allowed to cool to room temperature. The solid formed was collected by filtration, washed with a small quantity of MeOH and dried in vacuo to give 0.38 g brown powder.
