The present invention is based on the general formula [In the formula, R is alkenyl, alkoxycarbonyl, benzoyl, thiazolyl, naphthyl, or phenyl which may have a substituent (the substituent is one or two substituents selected from alkyl, alkoxy, and halogen). ; R' is 1-benzimidazolyl or 1-imidazolyl which may have a substituent (the substituent is alkyl); X is alkyl, alkoxy, halogen or alkoxycarbonyl; n is an integer of 0 to 3; Represent each. Dotted lines indicate that tautomers may exist. ] Regarding the compound represented by. This type of 1-imidazolylamidine is disclosed in Japanese Patent Application Laid-Open No. 50-13533; Japanese Patent Application Publication No. 53-124266;
2549899, etc., but the above compound () is not yet known. To specifically explain the terms used in the above definitions, alkyl includes methyl, ethyl, propyl,
Isopropyl, butyl, isobutyl, t-butyl, pentyl, etc.; Alkenyl such as vinyl, allyl, butenyl, pentenyl, etc.; Alkoxy such as methoxy, ethoxy, propoxy, isopropoxy, butoxy, t-butoxy, pentyloxy, etc.; Alkoxycarbonyl Examples include methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, butoxycarbonyl, and pentyloxycarbonyl; examples of halogen include chlorine, bromine, fluorine, and iodine. Target substance () is general formula It is obtained by reacting the compound represented by the formula (wherein R, X and n have the same meanings as defined above) with N,N'-thionyldiimidazole. This reaction is carried out in an inert solvent (e.g. methylene chloride, chloroform,
benzene, dimethylformamide, tetrahydrofuran, dioxane) under heating at room temperature to the boiling point of the solvent. The target substance () exhibits excellent anticancer activity and is useful as an anticancer agent. For example, N-(4-ethoxycarbonylphenyl)-N'-(2-thiazolyl)
-1-(1-imidazolyl)formamidine is
In an anticancer test using mouse leukemia P388, it showed a 37% survival rate (ILS). Other compounds showed similar biological activity. The dosage of Compound I for adult human beings is approximately 1.0 to 40 per day by oral administration.
mg/Kg. These are formulated into a solid or liquid dosage form together with diluents, excipients, disintegrants, solvents, and other additives commonly used in pharmaceuticals. Examples of the present invention are shown below. Example 1 Thionyl chloride was added to a solution consisting of 12.56 g of imidazole and 63 ml of methylene chloride while stirring under cooling with ice water.
Add 5.49g. After a few minutes, 1-(4-chlorophenyl)-3-(4-methoxyphenyl)thiourea
Add 3.0g and stir at room temperature for 1 hour. Add ice water to the reaction solution, neutralize with aqueous sodium hydrogen carbonate solution, and extract with methylene chloride. Wash the organic layer with water,
