Procedure

To a solution of 4-[4-(3-amino-2-fluorophenyl)-2-(1,1-dimethylethyl)-1,3-thiazol-5-yl]-2-pyrimidinamine (100 mg, 0.291 mmol) in DCM (2 ml), pyridine (0.4 mL, 4.95 mmol) was added followed by cyclohexylsulfonyl chloride (0.042 mL, 0.291 mmol). The solution was allowed to stir at rt for 24 h at rt. The solvent was removed and the concentrated residue was allowed to sit at rt overnight. The residue was then evaporated onto silica gel and chromatographed (1:9 MeOH:EtOAc in DCM). The title compound was obtained after trituration in diethyl ether (50 mg, 33% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 9.65 (s, 1H), 8.02 (d, J=5.1 Hz, 1H), 7.52 (t, J=7.7 Hz, 1H), 7.33 (t, J=6.4 Hz, 1H), 7.26 (t, J=7.9 Hz, 1H), 6.72 (s, 2H), 6.01 (d, J=5.1 Hz, 1H), 2.79-2.92 (m, 1H), 1.92-2.05 (m, 2H), 1.68 (d, J=12.6 Hz, 2H), 1.47-1.57 (m, 1H), 1.38 (s, 9H), 1.22-1.36 (m, 2H), 1.07-1.24 (m, 3H). MS (ESI): 490.2 [M+H]+.
