Reaction Steps

(S)-N-(3-(2-methylpyridin-3-yloxy)-5-(pyridin-2-ylthio)pyridin-2-yl)-3-(2,2,5,5-tetramethyl-1,3-dioxolane-4-yl)-1,2,4-thiadiazol-5-amine (145 mg, 0.2774 mmol) was dissolved in EtOH (5 mL), and 6M HCl (0.3 mL) was added. The reaction was stirred at ambient temperature for 2 hours and then at 70° C. for 2 hours. The reaction was cooled to ambient temperature and partitioned between CH2Cl2 and saturated aqueous sodium bicarbonate. The organic layer was dried, filtered, concentrated and purified over silica gel (10% methanol in EtOAc) to afford (S)-2-methyl-1-(5-(3-(2-methylpyridin-3-yloxy)-5-(pyridin-2-ylthio)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)propane-1,2-diol hydrochloride (111.7 mg, 0.215 mmol, 77.6% yield) as a pale yellow solid after HCl salt formation. Mass Spectrum (apci) m/z=465.2 (M+H−HCl).
