Procedure
To a solution of N-{3-[2-(3-aminooxetan-3-yl)-1,3-thiazol-5-yl]-5-methylphenyl}-4-(trifluoromethyl)pyrimidin-2-amine (Example 59, 25 mg, 0.061 mmol) in dioxane (600 uL), sulfamide (70 mg, 0.725 mmol) was added. The reaction mixture was stirred at 100° C. The resulting mixture was stirred at 100° C. for 4 days. The mixture was diluted with ethyl acetate, washed with saturated aqueous NaHCO3, followed by brine, dried (Na2SO4), filtered and concentrated. The residue was purified by column chromatography on silica (10-100% ethyl acetate in hexanes) and lyophilized to afford N-{3-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]oxetan-3-yl}sulfuric diamide (16.3 mg, 0.034 mmol, 54.6% yield) as a pale yellow solid. MS ESI: [M H]+ m/z 487.0. 1H NMR (500 MHz, DMSO-d6) δ 10.27 (s, 2H), 8.85 (m, 1H), 8.30 (s, 1H), 8.04 (s, 1H), 7.95 (s, 1H), 7.51 (s, 1H), 7.28 (m, 1H), 7.17 (s, 1H), 6.98 (s, 2H), 5.02 (m, 2H), 4.84 (m, 2H), 2.32 (s, 3H). rhSYK activity=+++
