Methanol → 2,2-Dimethyl-5-oxo-1-imidazolidineacetamide

Participants

Reaction Steps

To a solution of glycylglycinamide acetate (10 g) in methanol (250 ml) and acetone (125 ml), was added Amberlite IRA-68 resin (20 g) (available from Rohm & Haas, Philadelphia, USA). Amberlite is a registered trade mark and IRA-68 is a weakly basic resin. The suspension was stirred at room temperature for 1 hour, then resin was filtered off and the solution was evaporated under reduced pressure. The residue was suspended in refluxing acetone (250 ml) and methanol was added to obtain a clear solution, which was refluxed for 2 hours. Evaporation and trituration of the residue with acetone gave 6.85 g of the title compound.
