Participants

Reaction Steps

750 mg of glyoxylic acid methyl ester methyl alcoholate and 920 mg of N-cyclohexylurea were refluxed in 50 ml of a mixture of acetic acid and methanol (4:1) for 1 hour. After cooling, the solvent was removed by distillation and the residue was purified by column chromatography on silica gel. The obtained crude product was recrystallized from benzene to give 420 mg of 5-methoxy-3-cyclohexylhydantoin (compound 20) in the form of colorless needle crystals.
