Procedure

To a stirred solution of ethyl N-({5-iodo-2-[({3-methoxy-4-[(4-methoxyphenyl)methoxy]phenyl}methyl)amino]pyridin-3-yl}carbamothioyl)carbamate (2.30 g, 3.69 mmol) and triethylamine (1.30 g, 1.8 mL, 12.85 mmol) in tetrahydrofuran (20 mL) was added benzenesulfonyl chloride (0.93 g, 5.27 mmol). The resulting mixture was allowed to stir at room temperature. After 12 h, a precipitate had formed. The mixture was filtered, and the filtercake was washed with water (2×10 mL) and methanol (10 mL). The solids were dried to provide 1.50 g (69%) of ethyl(6-iodo-3-(3-methoxy-4-((4-methoxybenzyl)oxy)benzyl)-3H-imidazo[4,5-b]pyridin-2-yl)carbamate as a brown solid.
