Reaction Steps

To a solution of N-{3-[2-(1-aminocyclobutyl)-1,3-thiazol-5-yl]-5-methylphenyl}-4-(trifluoromethyl)pyrimidin-2-amine (Example 61B-1, 50 mg, 0.123 mmol) and acetic acid (7 μL, 0.123 mmol) in THF/water (1.6:1, 2.1 mL), potassium cyanate (10 mg, 0.123 mmol) was added. The reaction mixture was stirred overnight at room temperature and then concentrated. The residue was purified by column chromatography on silica (50-100% ethyl acetate in hexanes, 0-20% methanol in dichloromethane) and lyophilized to afford 1-{1-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]cyclobutyl}urea (31.3 mg, 0.068 mmol, 54.9%) as a white powder. MS ESI: [M+H]+ m/z 449.1. 1H NMR (500 MHz, DMSO-d6 δ 10.23 (s, 1H), 8.82 (d, J=4.9, 1H), 7.93 (s, 1H), 7.90 (s, 1H), 7.47 (s, 1H), 7.27 (d, J=4.9, 1H), 7.15-7.00 (m, 2H), 5.58 (s, 2H), 2.63-2.51 (m, 2H), 2.32 (m, 5H), 1.96 (m, 2H). rhSYK activity=+++
