실험 절차

A flask was charged with (S)—N-(5-(pyridin-2-ylthio)-3-(1,3,5-trimethyl-1H-pyrazol-4-yloxy)pyridin-2-yl)-3-(2,2,5,5-tetramethyl-1,3-dioxolan-4-yl)-1,2,4-thiadiazol-5-amine (0.233 g, 0.432 mmol), ethanol (10 mL), and 3M HCl (0.288 ml, 0.863 mmol). The reaction was heated to 75° C. for 1 hour and then concentrated in vacuo. Ether was added to the residue and the mixture was stirred for 2 minutes to precipitate the product. The mixture was decanted and the resulting solids were dried in vacuo to afford (S)-2-methyl-1-(5-(5-(pyridin-2-ylthio)-3-(1,3,5-trimethyl-1H-pyrazol-4-yloxy)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)propane-1,2-diol hydrochloride (0.248 g, 0.387 mmol, 89.6% yield) as yellow solid. Mass Spectrum (apci) m/z=500.1 (M+H−HCl).
