실험 절차

5-Chloro-2-methylsulfanyl-pyrrolo[2,1-f][1,2,4]triazine (54 mg, 0.27 mmol) was dissolved in 1,2-Dichloroethane (2.0 mL and then N-Iodosuccinimide (75 mg, 0.33 mmol) was added in one portion and the reaction was stirred in a vial at 60° C. overnight. The heterogenous mixture was powdered onto silica gel (0.75 g) and purified on ISCO (12 g, 0-5% EtOAc:Hex) to afford 5-Chloro-7-iodo-2-methylsulfanyl-pyrrolo[2,1-f][1,2,4]triazine (49 mg; Yield=56%) as a yellow solid. m.p. 216-220° C.; LCMS (Bruker, Fragile): 4.0 min, m/z=326; 1H-NMR (CDCl3): 8.55 (s, 1H), 6.90 (s, 1H), 2.63 (s, 3H).
