Procedure
To a solution of 6′-hydroxy-8′-methyl-2′H-spiro[cyclohexane-1,3′-imidazo[1,5-a]pyridine]-1′,5′-dione (3, 1 g, 4.03 mmol) in dimethylacetamide (20 mL) is added potassium carbonate (1.67 g, 12.09 mmol) and 4-bromopyrimidine (4, 0.77 g, 4.84 mmol). The reaction is stirred at 130° C. overnight. The resulting mixture is cooled to room temperature, poured into water and extracted with dichloromethane. The organic layer is dried over magnesium sulfate, filtered and concentrated. The crude is purified via column chromatography to afford 8′-methyl-6′-(pyrimidin-4-yloxy)-2′H-spiro[cyclohexane-1,3′-imidazo[1,5-a]pyridine]-1′,5′-dione (Cpd. No. 209).
