Reaction Steps

A mixture of 2-benzhydryl-2,5,7-triazaspiro[3.4]octane-6,8-dione (0.258 g, 0.839 mmol) and 10% palladium on carbon (0.179 g, 0.168 mmol) in 4 mL MeOH was treated with acetic acid (0.0961 mL, 1.68 mmol) and the slurry was stirred under a balloon containing hydrogen overnight. The reaction was filtered, rinsed with MeOH, and concentrated in vacuo to give an oil. Concentration from benzene gave a solid which was suspended in diethylether, sonicated, filtered, and dried in vacuo to give 2,5,7-triazaspiro[3.4]octane-6,8-dione acetate (0.117 g, 69.3% yield) as a white solid.
