Procedure

To a solution of 5-chloromethyl-2,4-dihydro-1,2,4-triazol-3-one (35 mg, 0.26 mmol) in 2-butanone, were added N2-(3-aminosulfonyl-4-fluorophenyl)-5-fluoro-N4-(4-hydroxyphenyl)-2,4-pyrimidinediamine (100 mg, 0.25 mmol) and potassium carbonate (35 mg, 0.25 mmol). The resulting mixture was microwaved at 140° C. for 5 hours, and then additional of 5-chloromethyl-2,4-dihydro-1,2,4-triazol-3-one was added as needed The reaction solvent was removed under a reduced pressure, and the residual was purified by column chromatography (silica gel, dichloromethane: methanol 8:2 v/v) to give 25 mg of N2-(3-aminosulfonyl-4-fluorophenyl)-5-fluoro-N4-[4-(2,4-dihydro-3-oxo-1,2,4-triazol-5-yl)methoxyphenyl]-2,4-pyrimidinediamine (76) as a light yellow solid. 1H NMR (D2O): δ 7.90-7.89 (d, J=3 Hz, 1H), 7.60-7.58 (d, J=6 Hz, 1H), 7.34 (bs, 2H), 7.24-7.18 (m, 2H), 7.05-7.02 (d, J=9.0 Hz, 2H), 6.65-6.62 (d, J=9.0 Hz, 2H), 5.11 (br s, 2H); LCMS (m/z): 491.05 (MH+).
