After 10 min, KI (22.5 g, 0.136 mol) in 30 mL of water was added dropwise at -5°C while maintaining the internal temperature below 10°C over the course of the addition. The reaction mixture was warmed to rt and 250 mL of EtOAc was added. The pH of the aqueous layer was adjusted to 11 by the addition of 50 mL of 6N NaOH, the layers were separated, and the organic layer was washed with 120 mL of 0.3M Na2S203. The EtOAc layer was concentrated and the concentrate was purified by column chromatography over silica gel (hexane/ EtOAc =25/1) to afford the title compound as a white solid (14.6 g, 87percent).

YieldReaction ConditionsOperation in experiment
96% With iodine; silver sulfate In ethanol at 20℃; for 24 h; PREPARATION IV
3-Amino-2-iodo-6-(trifluoromethyl)pyridine
3.85 g (12.3 mM) of silver sulfate are added, with stirring and at room temperature, to a solution of 2 g (12.3 mM) of 5-amino-2-(trifluoromethyl)pyridine in 100 ml of ethanol.
3.13 g of iodine are then added and the reaction mixture is stirred at room temperature for 24 hours.
The solid in suspension in the medium is removed by filtration and the filtrate is concentrated under reduced pressure.
The evaporation residue is taken up in 200 ml of dichloromethane and washed with 5percent sodium hydroxide solution, and then with water and dried over magnesium sulfate.
The solution obtained is concentrated under reduced pressure and 3.42 g of the expected compound are thus obtained in the form of a pink solid (yield=96percent).
