Acetaldehyde → 2-Methyl-5-oxo-1-imidazolidineacetamide

Participants

Reaction Steps

A solution of glycylglycinamide (0.5 g) and acetaldehyde (0.4 ml) in methanol (5 ml) was stirred at room temperature for 8 hours. Evaporation of the solvent gave a residue which was chromatographed on a silica gel column (eluant dichloromethane/methanol 75:25). The selected fractions were collected, evaporated to give the title compound (Rf=0.3, dichloromethane/methanol 7:3, silica gel plates). Mass spectrum (E.I., 70 eV, 1.5 mA), m/z=142 (M+ -CH3), 99.
