Reaction Steps

To ethyl 4-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]cyclohexanecarboxylate (0.60 g, 0.12 mmol) in tetrahydrofuran (0.61 mL) was added potassium hydroxide (1.2 mL, 1 M in methanol) and the reaction was stirred overnight at room temperature. Upon completion, the reaction was diluted with dichloromethane and washed twice with hydrochloric acid (2 M in water). The organic layer was dried under reduced pressure to give 2-({3-[2-(4-carboxycyclohexyl)-1,3-thiazol-5-yl]-5-methylphenyl}amino)-4-(trifluoromethyl)pyrimidin-1-ium chloride (0.060 g, 85% yield). MS ESI: [M+H]+ m/z 463.1. 1H NMR (500 MHz, DMSO-d6) δ 10.25 (s, 1H), 8.83 (d, J=5.2, 1H), 8.06-7.81 (m, 2H), 7.44 (s, 1H), 7.27 (d, J=5.8, 1H), 7.14 (s, 1H), 2.30 (s, 3H), 2.14-2.04 (m, 110, 2.03-1.83 (m, 4H), 1.82-1.61 (m, 3H), 1.55-1.33 (m, 2H). rhSYK activity=+++
