Reaction Steps
A mixture of 7-hydroxyisoquinoline (1.15 g, 7.9 mmol), ethylene carbonate (0.98 g, 11.1 mmol), powdered K2CO3 (0.65 g, 4.7 mmol) in dry DMF (20 mL) was stirred at 145° C. for two hours. The reaction was quenched with MeOH (1 mL), filtered and the solvent was removed under reduced pressure. The residue was taken up between alkaline water (K2CO3) and CHCl3. Concentration of the dried (MgSO4) organic phase afforded 1.4 g (94%) of the title compound as a yellow oil that solidified upon standing. Purity 91% (HPLC). Fragmenting mass analysis supports the stated structure.
