Reaction Steps

A mixture of N4-[2-(tert-butylcarbonyl)amino-3-methoxypyrid-6-yl]-2-chloro-5-fluoro-4-pyrimidineamine (65) (25 mg, 0.07 mmol) and 3-aminosulfonyl-4-methylaniline (15 mg) in methanol (1 mL) was shaken in a sealed tube at 100° C. for 48 h. The reaction mixture was then chromatographed (silica gel, CH2Cl2 then 2-4% 2N NH3/MeOH in CH2Cl2) to obtain N2-(3-aminosulfonyl-4-methylphenyl)-N4-(2-amino-3-methoxypyrid-6-yl)-5-fluoro-2,4-pyrimidinediamine (66). (Note: The N-tert-butylcarbonyl group was cleaved during this reaction to give free amine function). LCMS: purity: 90%; MS (m/z): 420 (MH+).
