Reaction Steps

A solution of (S)—N-((R)-1-(2-chloro-4-(3-((7-methoxyquinolin-4-yloxy)methyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)phenyl)-2,2,2-trifluoroethyl)-2-methylpropane-2-sulfinamide (62 mg, 100 μmol) in MeOH (2 mL) and 5M HCl (2 mL) was stirred at 35° C. for 18 h. LCMS suggests full conversion. Solvents removed under reduced pressure and residue dissolved in MeOH (20 mL). Si-Carbonate (1.3 g; 0.9 mmol) added to solution and stirred for 2 h. Filtrated isolated by filtration and reduced to a film under reduced pressure. Product purified on silica (4 g) eluting with 7% 2M NH3 in MeOH/DCM. MS (ESI pos. ion) m/z: 515 (MH+). Calc'd exact mass for C24H18ClF3N6O2: 514.
