実験手順

(4-Fluoro-phenyl)-imidazo[2,1-b][1,3,4]thiadiazol-2-yl-amine (0.117 g, 0.50 mmol) was suspended in N,N-dimethylformamide (3 mL) and N-iodosuccinimide (0.124 g, 0.55 mmol) was added in one portion. The reaction mixture was stirred at room temperature for 2 hours in the absence of light. The mixture was evaporated and the residue was purified by column chromatography (Biotage™/Flash, silica, methanol:dichloromethane 0.4:9.6 to 1:9) to give 0.13 g of (4-fluoro-phenyl)-(5-iodo-imidazo[2,1-b][1,3,4]thiadiazol-2-yl)-amine as an off-white solid (72% yield).
