Reaction Steps

Preparation of 3-(4-fluorophenoxy)-N-(3-(piperidin-4-ylmethyl)-1,2,4-thiadiazol-5-yl)-5-(thieno[3,2-b]pyridin-2-amine trihydrochloride: A 10 mL round-bottomed flask was charged with tert-butyl 4-((5-(3-(4-fluorophenoxy)-5-(thieno[3,2-b]pyridin-7-ylthio)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)methyl)piperidine-1-carboxylate (52.2 mg, 0.0802 mmol) and a 1:1 mix of methanol and CH2Cl2 (4 mL). 4N HCl in dioxane (2 mL) was added and the reaction stirred at room temperature for 10 minutes. The solvent was removed to afford crude 3-(4-fluorophenoxy)-N-(3-(piperidin-4-ylmethyl)-1,2,4-thiadiazol-5-yl)-5-(thieno[3,2-b]pyridin-7-ylthio)pyridin-2-amine trihydrochloride (52.9 mg, 100%).
