Procedure

To a solution of tert-butyl 2-(3-((7-methoxyquinolin-4-yloxy)methyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)-6,7-dihydrothieno[3,2-c]pyridine-5(4H)-carboxylate (0.27 g, 0.50 mmol) (prepared according to general method A) was added trifluoroacetic acid (0.77 mL, 10 mmol). The mixture was stirred at room temperature for 90 minutes, then was concentrated, taken up in 2.0 M ammonia in methanol and purified by MPLC (eluted with a gradient of 0 to 10% methanol in dichloromethane) to yield the product as a pink solid. MS m/z=445.0 [M+1]+ Calc'd for C23H20N6O2S: 444.51.
