Reaction Steps

1-(3-Methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)guanidine (418 mg, 1.36 mmol) and potassium carbonate (469 mg, 3.40 mmol) in EtOH (8mL) were stirred for 10min at 50° C. Ethyl 2-oxo-2-(4-oxotetrahydro-2H-pyran-3-yl)acetate (272 mg, 1.36 mmol) was added slowly and the reaction was stirred at 50° C. over night. The crude product was partitioned between DCM and water. The organic phase was dried and solvent evaporated and used as such in the next step. MS (ES+) m/z 410.0 (M+H)+
