Triethylamine → ethyl N-({5-iodo-2-[({3-methoxy-4-[(4-methoxyphenyl)methoxy]phenyl}methyl)amino]pyridin-3-yl}carbamothioyl)carbamate

Participants

Reaction Steps

To a stirred solution of 5-iodo-N2-(3-methoxy-4-((4-methoxybenzyl)oxy)benzyl)pyridine-2,3-diamine (Example 3-16-2) (2.00 g, 4.07 mmol) and triethylamine (1.30 g, 1.8 mL, 12.85 mmol) in tetrahydrofuran (20 mL) was added O-ethyl carbonisothiocyanatidate (1.07 g, 8.20 mmol). The reaction mixture was allowed to stir at room temperature. After 3 h, the mixture was filtered, and the filtrate was concentrated to provide 2.30 g of ethyl N-({5-iodo-2-[({3-methoxy-4-[(4-methoxyphenyl)methoxy]phenyl}methyl)amino]pyridin-3-yl}carbamothioyl)carbamate as a yellow oil.
