실험 절차

To a solution of methyl Z-4-[[2-butyl-5-[(1-butyl-2,5-dioxo-4-imidazolidinylidene)methyl]-1H-imidazol-1-yl]methyl]benzoate (0.569 g, 1.2 mmol) in DMF (5 mL) is added K2CO3 (2.0 g, 15 mmol). After stirring for 5 minutes 2-amino-4-chloromethylthiazole hydrochloride (0.222 g, 1.2 mmol) is added. The mixture is stirred for 48 hours and then filtered. The filtrate is concentrated in vacuo and dissolved in methylene chloride (30 mL). This solution is washed with water and dried over K2CO3 and charcoal. A viscous oil is obtained by evaporation of the solvents in vacuo. This oil is dissolved in ether and treated with ethereal HCl to precipitate a gum which is collected by decantation. This gum is recrystallized from 2-propanol/ether.
