Reaction Steps

tert-Butyl 4-(5-(4-(5-((2-(dimethylamino)ethyl)carbamoyl)-2,4-dimethylpyridin-3-yloxy)-5-bromopyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)piperidine-1-carboxylate (0.025 g, 0.037 mmol) was dissolved in a mixture of methanol:dichloromethane (1 mL each). HCl (4N in dioxane, 0.5 mL, 2.0 mmol) was added. The reaction stirred overnight. The solution was concentrated to give 5-(5-bromo-2-(3-(piperidin-4-yl)-1,2,4-thiadiazol-5-ylamino)pyridin-4-yloxy)-N-(2-(dimethylamino)ethyl)-4,6-dimethylnicotin-amide dihydrochloride (0.028 g, 100% yield) as an off-white solid. 1H NMR (400 MHz, DMSO-d6) δ 1.87-1.93 (m, 2H), 2.06-2.14 (m, 2H), 2.22 (s, 3H), 2.34 (s, 3H), 2.83 (s, 3H), 2.84 (s, 3H), 2.96-3.08 (m, 2H), 3.23-3.32 (m, 4H), 3.44-2.52 (m, 1H), 3.62-3.73 (m, 2H), 6.37 (s, 1H), 8.64 (s, 1H), 8.67 (s, 1H), 8.70 (s, 1H), 9.0 (s, 1H), 9.03 (t, 1H), 10.50 (s, 1H), 11.88 (s, 1H).
