Reaction Steps
To a solution of 6′-((4-methoxybenzyl)thio)-8′-methyl-2′H-spiro[cyclohexane-1,3′-imidazo[1,5-a]pyridine]-1′,5′-dione (3, 3.3 g, 8.58 mmol) in chloroform (40 mL) is added methanesulfonic acid (3 mL, 46.23 mmol). The reaction is stirred at 50° 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 6′-mercapto-8′-methyl-2′H-spiro[cyclohexane-1,3′-imidazo[1,5-a]pyridine]-1′,5′-dione (4).
