Reaction Steps
To the solution of N-methyl-4-(2-(methylsulfinyl)benzo[d]thiazol-6-yloxy)picolinamide (25 mg, 0.072 mmol, 1.0 eq) in 2 mL of NMP was added (4-((4-methylpiperazin-1-yl)methyl)phenyl)methanamine (23 mg, 0.108 mmol, 1.5 eq) and DIPEA (37 μL, 0.216 mmol, 3.0 eq) and reaction mixture heated at 80° C. in oil bath for 12 hours. Thereafter, the product was purified via reverse phase HPLC. LC/MS (m/z) [503.1] (MH+).
