Procedure

(S)-N-(3-(2-methylpyridin-3-yloxy)-5-(pyridin-2-ylthio)pyridin-2-yl)-3-(2,2,4-trimethyl-1,3-dioxolan-4-yl)-1,2,4-thiadiazol-5-amine (55 mg, 0.108 mmol) was dissolved in EtOH (3 mL). 1M HCl (0.3 mL) was added and the mixture was stirred at ambient temperature for 24 hours. Additional 1M HCl (0.3 mL) was added and the mixture was stirred overnight. The mixture was partitioned between saturated aqueous sodium bicarbonate and CH2Cl2, dried over sodium sulfate, filtered and concentrated. The residue was purified over silica gel (15% methanol in EtOAc) to afford (S)-2-(5-(3-(2-methylpyridin-3-yloxy)-5-(pyridin-2-ylthio)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)propane-1,2-diol hydrochloride (34.9 mg, 0.0691 mmol, 63.9% yield) as a white solid after HCl salt formation. Mass Spectrum (apci) m/Z=451.1 (M+H—H2O—HCl) (100) and 469.1 (M+H—HCl) (30).
