tert-Butyl 2-oxo-2-(4-(5-(3-phenoxy-5-(pyridin-2-ylthio)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)piperidin-1-yl)ethylcarbamate (0.098 g, 0.16 mmol) was dissolved in CH2Cl2:MeOH (1:1, 20 mL) and added 5 mL of 4M HCl in dioxane and stirred for 2 hours. The reaction was concentrated and dried in high vacuum oven to provide 2-amino-1-(4-(5-(3-phenoxy-5-(pyridin-2-ylthio)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)piperidin-1-yl)ethanone dihydrochloride (0.081 g, 78% yield). 1H NMR (d6-DMSO) δ 12.34 (s, 1H), 8.39 (d, 1H), 8.37 (m, 1H), 8.13 (m, 3H), 7.67 (dt, 1H), 7.48 (d, 1H), 7.43 (t, 2H), 7.21-7.11 (m, 5H), 4.32 (d, 1H), 3.90 (m, 2H), 3.70 (m, 2H), 3.48 (m, 1H), 3.26-3.02 (m, 2H), 2.94 (t, 1H), 2.06 (d, 2H), 1.76-1.53 (m, 2H).
