실험 절차

Approximately 4.36 g. of 1-(2-methoxyethyl)-4-phenyl-4-imidazolin-2-one, 3 g. of triethylamine and 3 g. of benzoyl chloride are refluxed together for three hours in chloroform. The solution is cooled, washed with water, dried and the solvent removed to give an oil which is the O-benzoyl ester. The ester is refluxed for three hours in 20 ml. of xylene. The xylene is removed at reduced pressure. Recrystallization from ether gives the title compound as a pale yellow solid; m.p. 112°-117° C.
