Procedure

A mixture of 8-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]-1,4-dioxaspiro[4.5]decan-8-ol (60 mg, 0.122 mmol), sodium azide (23.76 mg, 0.365 mmol) and methanesulfonic acid (95 μL, 1.462 mmol) in CHCl3 (1.2 mL) was heated at 65° C. for 1 h and cooled to room temperature. The mixture was treated with water, and extracted with ethyl acetate. The combined organics were dried, filtered, concentrated and purified by flash chromatography to afford 5-hydroxy-5-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]azepan-2-one (36 mg, 0.078 mmol). APCI: [M+H]+ m/z 464.2. 1H NMR (600 MHz, CDCl3): δ 8.63 (d, J=4.9, 1H), 7.89 (s, 1H), 7.83 (s, 1H), 7.62 (s, 1H), 7.26 (s, 1H), 7.05 (s, 1H), 7.03 (d, J=4.9, 1H), 6.21 (s, 1H), 3.81 (s, 1H), 3.46 (s, 1H), 3.21-3.03 (m, 2H), 2.41 (dd, J=7.5, 14.4, 1H), 2.37 (s, 3H), 2.24 (t, J=13.3, 1H), 2.18-2.04 (m, 3H). rhSYK activity=+++
