Reaction Steps
To 6-(N-(4-bromobutyl)methylsulfonamido)-5-cyclopropyl-N-methyl-2-(p-tolyl)furo[2,3-b]pyridine-3-carboxamide (4.5 mg, 8.42 μmol) was added ethyl 2-(methylsulfonyl)acetate (1.399 mg, 8.42 μmol) and CESIUM CARBONATE (5.49 mg, 0.017 mmol) and KI (1.398 mg, 8.42 μmol) and DMF Heated at 120° C. 20 min. Added water and extracted with EtOAc. Conc. on vac to oil. Added 3 mL ACN and 1 mL water. Filtered with 0.45μ filter Purified via HPLC C18 40-100% ACN/H2O (0.1% NH4OH) 40 mL/min over 10 min. to give ethyl 6-(N-(5-cyclopropyl-3-(methylcarbamoyl)-2-(p-tolyl)furo[2,3-b]pyridin-6-yl)methylsulfonamido)-2-(methylsulfonyl)hexanoate.
