Reaction Steps

To a solution of (S)-methyl 3-(6-(3-(1,4-dioxaspiro[4.5]decan-2-yl)-1,2,4-thiadiazol-5-ylamino)-5-(1,3,5-trimethyl-1H-pyrazol-4-yloxy)pyridin-3-ylthio)propanoate (0.420 g, 0.749 mmol) in THF (10 mL) was added potassium 2-methylpropan-2-olate (2.36 ml, 2.36 mmol) and the reaction was stirred at ambient temperature for 5 minutes. 1-Bromo-2-methoxyethane (0.132 g, 0.899 mmol) (as a solution in 2 mL THF) and DMF (1 mL) were added and the reaction was stirred for 20 minutes at ambient temperature. The solution was quenched with water, extracted with CH2Cl2, dried over sodium sulfate, filtered and concentrated. The residue was purified over silica gel (100% EtOAc) to afford (S)-N-(5-(2-methoxyethylthio)-3-(1,3,5-trimethyl-1H-pyrazol-4-yloxy)pyridin-2-yl)-3-(1,4-dioxaspiro[4.5]decan-2-yl)-1,2,4-thiadiazol-5-amine (0.200 g, 50.1% yield).
