Reaction Steps

2-Chloro-5-fluoro-N4-[4-(prop-2-ynylaminosulfonylmethyl)phenyl]-4-pyrimidineamine (34 mg, 0.096 mmol), 3-aminobenzenesulfonamide (33 mg, 0.19 mmol), and trifluoroacetic acid (11 μL, 0.14 mmol) were combined with iPrOH (0.40 mL) in a sealed vial and heated at 100° C. for 4 h. The reaction mixture was cooled to room temperature and diluted with 1N HCl (80 mL). The crude product was isolated by filtration. Further purified by column chromatography (silica gel, dichloromethane ramped to methanol:dichloromethane (3:100)) provided N2-(3-aminosulfonylphenyl)-5-fluoro-N4-[4-(prop-2-ynylaminosulfonylmethyl)phenyl]-2,4-pyrimidinediamine (I-4) as an off-white solid. 1H NMR (DMSO-d6): δ 9.57 (s, 1H), 9.47 (s, 1H), 8.15-8.08 (m, 2H), 7.99-7.95 (m, 1H), 7.84 (d, J=8.4 Hz, 2H), 7.62 (t, J=5.7 Hz, 1H), 7.43-7.32 (m, 4H), 7.26 (s, 2H), 4.35 (s, 2H), 3.79-3.75 (m, 2H), 3.35 (t, J=2.4 Hz, 1H); LCMS: purity: 96%; MS (m/e): 492 (MH+).
