Procedure

To a solution of 4-(5-chloropyridin-3-yl)-2-[(4aR,7aR)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl]-7-hydroxy-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine-6-carbonitrile (24.5 mg, 0.048 mmol) in DMF (2 mL) were added Cs2CO3 (31.5 mg, 0.097 mmol) and MeI (6 μL, 0.097 mmol). The reaction was stirred at room temperature for 15 minutes and then diluted with EtOAc (40 mL) and washed with water (10 mL) and brine (10 mL). The organic layer was dried over Na2SO4, filtered, and concentrated. The residue was purified on a silica gel column with 0 to 100% EtOAc/hexanes to afford 4-(5-chloropyridin-3-yl)-2-[(4aR,7aR)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl]-7-methoxy-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine-6-carbonitrile. MS ESI calc'd for C28H33ClN6O2 [M+H]+=521. found=521.
