Reaction Steps

tert-Butyl 3-(5-(3-(2-ethylpyridin-3-yloxy)-5-(3-methoxy-3-oxopropylthio)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)-8-azabicyclo[3.2.1]octane-8-carboxylate (115 mg, 0.183 mmol) was dissolved in THF (4 mL) and nitrogen was bubbled through the solution for 3 minutes. Potassium 2-methylpropan-2-olate (51.5 mg, 0.459 mmol) was added and the reaction was stirred at ambient temperature for 30 seconds. 1-Bromo-2-methoxyethane (19.0 μL, 0.202 mmol) was added and the reaction was stirred at ambient temperature for 30 minutes. The reaction was partitioned between EtOAc and aqueous NH4Cl. The organic layer was dried over sodium sulfate, filtered, concentrated and purified on silica gel (80% EtOAc in hexanes) to afford tert-butyl 3-(5-(3-(2-ethylpyridin-3-yloxy)-5-(2-methoxyethylthio)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)-8-azabicyclo[3.2.1]octane-8-carboxylate (101 mg, 0.169 mmol, 91.9% yield).
