A solution of dimethyl carbonate (20 mL) was treated with NaH (3 g, 60% dispersed in oil, 75 mmol) and heated to 85° C. To the mixture was dropwise added a solution of bezosuberone (3 g, 18.75 mmol) in dimethyl carbonate (10 mL). The resulting mixture was refluxed for 3 hours, cooled to 0° C., quenched with HCl (1N) (100 mL) and extracted with ether. The organic layer was washed with NaHCO3 and brine, dried (MgSO4) and concentrated to provide the title compound as a brownish oil.
