Reaction Steps
6-Amino-3-pyridinecarbonitrile (10.0 g, 0.081 mol), silver trifluoroacetate (25.5 g, 0.115 mol) and 160 ml of 1,2-dichloroethane are combined in a flask and heated under reflux for 5 h. Iodine (29.5 g, 0.116 mol) is added, and the mixture is heated for a further 18 h. After cooling, the mixture is filtered and partitioned between water and dichloroethane. Organic and aqueous phase are filtered through Celite. The aqueous phase is extracted to exhaustion, and the combined organic phases are combined, dried and evaporated. The residue is dissolved in ethyl acetate and washed with sodium thiosulfate solution. Removal of the solvent gives 6.6 g of yellowish crystals product. These are reacted further without further purification; HPLC: 2.57 min; LCMS: 246 [M+H]+.
