실험 절차

(S)-N-(3-(2-ethylpyridin-3-yloxy)-5-(pyridin-2-ylthio)pyridin-2-yl)-3-(1,4-dioxaspiro[4.5]decan-2-yl)-1,2,4-thiadiazol-5-amine (0.600 g, 1.09 mmol) was dissolved in ethanol (25 ml) and water (600 mg) and concentrated HCl (600 mg) were added. The mixture was heated to reflux for 2 hours, concentrated in vacuo, dissolved and concentrated with EtOH (2×50 mL). The material was triturated from acetonitrile to afford (S)-1-(5-(3-(2-ethylpyridin-3-yloxy)-5-(pyridin-2-ylthio)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)ethane-1,2-diol (0.420 g, 0.90 mmol, 82%) as a solid. Mass Spectrum (apci) m/z=469.1 (M+H—HCl).
