실험 절차

A mixture consisting of 4.9 gm (0.02 mol) of 1-methyl-2-(2,6-dichlorophenyl-imino)-imidazolidine, 2.1 ml of allyl bromide (125% of the stoichiometrically required amount), 2.7 gm of sodium carbonate and 25 ml of ethanol was refluxed for 5.5 hours while stirring. Thereafter, the reaction mixture was filtered, the filtrate was evaporated in vacuo to dryness, the residue was dissolved in dilute (about 1 N) hydrochloric acid, and the resulting solution was extracted with ether (the ethanol extracts were discarded). The acidic aqueous phase was then fractionally extracted with ether at stepwisely increasing pH-values (addition of 2 N sodium hydroxide). The thin-layer chromatographically uniform fractions were combined, dried over magnesium sulfate, and the ether was evaporated in vacuo, leaving an oil which crystallized gradually throughout. 2.3 gm (40.5% of theory) of the compound of the formula ##STR7## having a melting point of 59°-61° C. were obtained.
