1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → Methyl 3-[4-(N-{[6-amino-5-({3-[(3-methyl-2-furoyl)amino]phenyl}-ethynyl)pyridin-3-yl]carbonyl}-S-methylsulfonimidoyl)phenyl]propanoate

Temperatur

60 °C

6-Amino-5-((3-(3-methylfuran-2-carboxamido)phenyl)ethynyl)nicotinic acid (0.1 g, 0.277 mmol) was dissolved in DMF (2.8 mL). EDCI (0.64 g, 0.332 mmol) and DMAP (3.42 mg, 0.028 mmol) were then added and the reaction mixture was stirred at 60° C. for 20 minutes. Methyl 3-(4-(S-methylsulfonimidoyl)-phenyl)propanoate (0.068 g, 0.277 mmol) was then added, and the reaction was allowed to stir for 3 hours at 60° C. The mixture was cooled to room temperature then taken up in EtOAc (10 mL) and extracted with brine (3×10 mL). The organic layer was dried over anhydrous Na2SO4(s), filtered and concentrated in vacuo. The crude product was then purified over silica purified via column chromatography (gradient eluant mixture of MeOH in EtOAc: 0% to 10% MeOH) to give the title compound (0.060 g, 37%).
