Reaction Steps

To a solution of (S)-N-(5-(cyclopropylmethylthio)-3-(2-methylpyridin-3-yloxy)-pyridin-2-yl)-3-(1,4-dioxaspiro[4.5]decane-2-yl)-1,2,4-thiadiazol-5-amine (0.30 g, 0.586 mmol) in ethanol (20 mL) was added 1 M HCl (0.87 mL) and the reaction heated to 80° C. for 2 hours. The reaction was cooled and concentrated in vacuo and the solid triturated with ethanol The solid was dried in vacuo to afford (S)-1-(5-(5-(cyclopropylmethylthio)-3-(2-methylpyridin-3-yloxy)-pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)ethane-1,2-diol (0.146 g, 0.338 mmol, 57.7% yield) as the mono HCl salt. Mass Spectrum (apci) m/z=432.0 (M+H−HCl).
