Trifluoromethanesulfonic acid → 5-Iodo-6-methyl-N-[4-(methylsulfonyl)benzyl]-2-oxo-1-[3-(trifluoro-methyl)phenyl]1,2-dihydropyridine-3-carboxamide

Participants

Reaction Steps

To a solution of 6-methyl-N-[4-(methylsulfonyl)benzyl]-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2-dihydropyridine-3-carboxamide (200 mg, 0.43 mmol) in MeCN (1.5 ml) at RT and under argon, was added trifluoromethanesulfonic acid (1 ml) followed by N-iodosuccinimide (97 mg, 0.43 mmol). After 45 min, the reaction mixture was diluted with DCM, washed with aqueous NaHCO3, with aqueous NaS2O4 and water, dried (Na2SO4), and evaporated to give the title compound SM1 (200 mg).
