Versuchsvorschrift

4-[2-(benzyloxy)-5-chloropyridin-3-yl]-6-chloro-2-[(trans)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl]-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine (racemic, 450 mg, 0.74 mmol), zinc cyanide (43 mg, 0.37 mmol) and Pd(PPh3)4 (128 mg, 0.11 mmol) were placed in a dry vial. Degassed DMA (4 mL) was added to the reaction, and the reaction was placed under an atmosphere of Ar, sealed, and heated at 90° C. for 12 hours. The reaction was then cooled to room temperature, and cold water was added slowly. The aqueous layer was extracted with EtOAc. The combined organic layers were dried over Na2SO4, filtered, and concentrated under reduced pressure. Purification of the residue on a silica gel column (0 to 50% EtOAc/hexanes) afforded 4-[2-(benzyloxy)-5-chloropyridin-3-yl]-2-[(trans)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl]-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine-6-carbonitrile as a racemic mixture. The enantiomers were separated on a chiral OD column using 2% IPA/98% heptanes. MS ES calc'd. for C34H37ClN6O2 [M+H]+ 597. found 597.
