Reaction Steps

tert-Butyl 1-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]cyclopropanecarboxylate (375 mg, 0.787 mmol) was taken up in CH2Cl2 (12 mL) before adding TFA (3 mL). The reaction was stirred at room temperature overnight. The reaction was evaporated to dryness, and the residue was azeotroped with DCE (3×) to provide 1-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]cyclopropanecarboxylic acid (TFA salt) (421 mg, 100%) as a yellow solid. MS ESI: [M+H]+ m/z 421.0. 1H NMR (600 MHz, DMSO-d6) δ 13.15 (s, 1H), 10.21 (s, 1H), 8.80 (d, J=4.8, 1H), 7.95 (s, 1H), 7.87 (s, 1H), 7.44 (s, 1H), 7.25 (d, J=4.9, 1H), 7.12 (s, 1H), 2.29 (s, 3H), 1.81-1.62 (m, 4H). rhSYK activity=+++
