実験手順

A mixture of 2-[3-(2-methanesulfinyl-pyrimidin-4-yl)-imidazo[1,2-a]pyridine-8-yl]-propan-2-ol (0.15 g) and N-(4-amino-cyclohexyl)-methanesulfonamide (0.325 g) in NMP (1.5 mL) was treated with TEA (0.33 mL) and heated at 105° C. for 18 h. The reaction mixture was then cooled to RT and diluted with water. The resulting precipitate was filtered, washed with water, and dried. The product was purified by ISCO using 100% DCM to 15% MeOH/DCM. Pure fractions were collected, concentrated, and titurated with EtOAc. The resulting solid was filtered and dried at 50° C. under vacuum overnight to provide N-(4-{4-[8-(1-hydroxy-1-methyl-ethyl)-imidazo[1,2-a]pyridine-3-yl]-pyrimidin-2-ylamino}-cyclohexyl)-methanesulfonamide (compound 3, 84.9 mg).
