実験手順

DMF (4 mL) was added to a vial containing 4-(5-chloropyridin-3-yl)-3-[(trans-4-methylcyclohexyl)methyl]-2-(phenylamino)-3H-imidazo[4,5-c]pyridine-6-carbonitrile (200 mg, 0.438 mmol), followed by methyl iodide (68 mg, 0.481 mmol) and potassium carbonate (121 mg, 0.877 mmol), and the vial was sealed and heated to 60° C. for 2 hours. The reaction mixture was cooled to room temperature, diluted with ethyl acetate, and washed with water and brine. The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography using 15% ethyl acetate/petroleum ether as eluent to afford 4-(5-chloropyridin-3-yl)-3-[(trans-4-methylcyclohexyl)methyl]-2-[methyl(phenyl)amino]-3H-imidazo[4,5-c]pyridine-6-carbonitrile. MS ES/APCl calc'd. for C27H27ClN6 [M+H]+ 471. found 471.
