1,3-dichloro-7-methoxyisoquinoline (2.00 g, 8.8 mmol, 1.0 eq.) was dissolved in 30 mL anhydrous toluene and sodium benzyloxide (2.30 g, 17.6 mmol, 2.0 eq.) was added. The mixture was heated to 80° C. for 18 h. TLC indicated the reaction was complete. The mixture was concentrated to give the crude product, which was purified by chromatography on silica gel (eluted with petroleum ether) to give 2.20 g of xxxvii-a as a white solid (84.6%). LCMS m/z=300.1, 302.0 (M+1) (Method B) (retention time=2.23 min).
