Procedure

tert-Butyl 4-(2-(3-phenoxy-5-(thieno[3,2-b]pyridin-7-ylthio)pyridin-2-ylamino)thiazol-4-yl)piperidine-1-carboxylate was dissolved in 1:1CH2Cl2:methanol and 4N HCl in dioxane added and stirred for 1 hour at room temperature. The reaction was concentrated and the residue was partitioned between CH2Cl2 and saturated aqueous sodium bicarbonate. The organic layer was dried over sodium sulfate, filtered and concentrated to afford 3-phenoxy-N-(4-(piperidin-4-yl)thiazol-2-yl)-5-(thieno[3,2-b]pyridin-7-ylthio)pyridin-2-amine (238 mg, 52.5% yield over 2 steps) as a white solid
