Методика

To a vial were added ((2S,4R)-4-methoxypyrrolidin-2-yl)methanol, HCl (0.303 g, 1.81 mmol), 2-bromo-4-(5-chloropyridin-3-yl)-3-((trans-4-methylcyclohexyl)methyl)-3H-imidazo[4,5-c]pyridine-6-carbonitrile (Preparative Example 3.1) (0.805 g, 1.810 mmol), potassium fluoride (0.210 g, 3.62 mmol), DMSO (4 ml) and DIEA (0.948 ml, 5.43 mmol). The reaction vial was capped and heated to 100° C. for 8 h. The reaction mixture was cooled to room temperature, diluted with ethyl acetate, and washed with water and then brine. The organic layer was dried over sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by silica gel chromatography (0-100% ethyl acetate/hexanes, linear gradient) to afford 4-(5-chloropyridin-3-yl)-2-((2S,4R)-2-(hydroxymethyl)-4-methoxypyrrolidin-1-yl)-3-((trans-4-methylcyclohexyl)methyl)-3H-imidazo[4,5-c]pyridine-6-carbonitrile. MS ESI calc'd. for C26H31ClN6O2 [M+H]+ 495. found 495.
