FIELD: chemistry.
SUBSTANCE: invention refers to method of production of C-phosphorylated alkylamidines serving as parent compounds of biologically active compounds for medicine and agriculture, of formula: 
where R1=C3-C4alkyl or isoalkyl; R2=CH3, C6H5; R3=C2-C4-alkyl or isoalkyl; R4=H, CH3, C3H7, C6H5, COOC2H5. Method includes in production of sodium derivatives of C-phosphorylated alkylamidines resulted from reaction of C-phosphorylated acetamidine with sodium. Produced sodium derivative is alkylated with alkylhalogenide in dioxane medium at mole ratio sodium:C-phosphorylated acetamidine:alkylhalogenide (1:1:1÷1.1), respectvely at temperature 20÷50°C.
EFFECT: production of new C-phosphorylated alkylamidines with high yield exceeding 78%.
