Reaction Steps

To a vial was added 2-bromo-4-(5-chloropyridin-3-yl)-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine-6-carbonitrile (Preparative Example 3.1, 90 mg, 0.202 mmol), (4aR,7aR)-octahydrocyclopenta[b][1,4]oxazine (51.5 mg, 0.405 mmol), potassium fluoride (58.8 mg, 1.01 mmol), DMSO (0.62 mL), and N,N-diisopropylethylamine (0.18 mL, 1.01 mmol). The vial was sealed and heated to 100° C. for 16 hours. 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-((4aR,7aR)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl)-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine-6-carbonitrile. MS ESI calc'd. for C27H31ClN6O [M+H]+ 491. found 491.
