실험 절차

A solution of 1-(2-bromoacetyl)-2,2-dimethyl-4-imidazolidinone (2 g) in 33% ammonia solution (80 ml) was stirred at room temperature overnight. After evaporation under reduced pressure, the residue was dissolved in dry ethanol and evaporated again to give 1-(2-aminoacetyl)-2,2-dimethyl-4-imidazolidinone hydrobromide as a white deliquescent powder (Rf 0.33, n-butanol/water/acetic acid 6:2:2, silica gel plates). The latter compound can also be prepared using the chloroacetyl derivative in a similar procedure.
