Reaction Steps

A flask was charged with (S)-N-(5-(2-methoxyethylthio)-3-(1,3,5-trimethyl-1H-pyrazol-4-yloxy)pyridin-2-yl)-3-(1,4-dioxaspiro[4.5]decane-2-yl)-1,2,4-thiadiazol-5-amine (0.200 g, 0.375 mmol), 3M HCl (0.751 ml, 0.751 mmol), and ethanol (5 mL). The reaction was heated to 80° C. for 1 hour and then cooled to ambient temperature. The reaction was concentrated in vacuo and purified using reverse phase chromatography (5 to 95% acetonitrile in water) to afford (S)-1-(5-(5-(2-methoxyethylthio)-3-(1,3,5-trimethyl-1H-pyrazol-4-yloxy)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)ethane-1,2-diol hydrochloride (0.165 g, 0.298 mmol, 79.4% yield) as white solid after HCl salt formation. Mass Spectrum (apci) m/z=453.1 (M+H−HCl).
