To a solution of dimethylamine hydrochloride (580 mg, 7.25 mmol) and sodium bicarbonate (812 mg, 9.67 mmol) in EtOH:water (4 mL:2 mL) was added 6-chloro-4-(5-chloro-2-fluoropyridin-3-yl)-2-[(trans)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl]-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine (racemic) (125 mg, 0.24 mmol). The reaction was heated to 90° C. for 5 hours. The reaction was then concentrated and diluted with EtOAc. The organic layer was washed with water and brine, dried over sodium sulfate, filtered, and concentrated. Purification of the residue on a silica gel column (0 to 45% EtOAc/hexanes) afforded 5-chloro-3-{6-chloro-2-[(trans)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl]-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridin-4-yl}-N,N-dimethylpyridin-2-amine (racemic). MS ES calc'd. for C28H36Cl2N6O [M+H]+ 543. found 543.
