실험 절차

In 1 L of absolute ethanol was added (S)—N-(3-(2-methylpyridin-3-yloxy)-5-(pyridin-2-ylthio)pyridin-2-yl)-3-(1,4-dioxaspiro[4.5]decan-2-yl)-1,2,4-thiadiazol-5-amine (41 g, 76.7 mmol) and the reaction was heated to 80° C. 41 mL of aqueous HCl (11.6 mL of concentrated HCl diluted in water) was added. After 2 hours, the resultant solid material was hot filtered, washed with ethanol (200 mL) and dried in vacuo to yield crude product as a solid which contained about 2% starting material. The solids were suspended in EtOH (1 L) and heated to 80° C. followed by 41 mL of aqueous HCl (11.6 mL of concentrated HCl diluted in water). After 3.5 hours the resultant solid material was hot filtered, washed with ethanol (200 mL) and dried in vacuo and to afford (S)-1-(5-(3-(2-methylpyridin-3-yloxy)-5-(pyridin-2-ylthio)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)ethane-1,2-diol hydrochloride (35 g, 85%). Mass Spectrum (apci) m/z=455.2 (M+H−HCl).
