Participants

Reaction Steps

To a solution of 6′-(hydrazono(pyrimidin-4-yl)methyl)-8′-methyl-2′H-spiro[cyclohexane-1,3′-imidazo[1,5-a]pyridine]-1′,5′-dione (4, 100 mg, 0.28 mmol) in toluene (4 mL) is added potassium tert-butoxide (94 mg, 0.84 mmol). The reaction is refluxed overnight. The resulting mixture is cooled to room temperature, diluted with dichloromethane and is hed with 1 M ammonium chloride solution. The organic layer is dried over magnesium sulfate, filtered and concentrated. The crude is purified via HPLC to afford 8′-methyl-6′-(pyrimidin-4-ylmethyl)-2′H-spiro[cyclohexane-1,3′-imidazo[1,5-a]pyridine]-1′,5′-dione (Cpd. No. 212).
