Intermediates II can be prepared according to the method described in JP2000007662, U.S. Pat. No. 4,977,264, U.S. Pat. No. 6,090,815, US20040092402, JP09124613, U.S. Pat. No. 5,468,751, U.S. Pat. No. 4,985,426, U.S. Pat. No. 4,845,097, Recueil des Travaux Chimiques des Pays-Bas (1978), 97(11), Pages 288-92.
The preparation of intermediates III refers to the three methods shown as follows according to the different definition of R5 and R6.
Intermediates III, when R4═R5═R6═H, are commercially available, or are prepared according to the method described in CN1312250A;
Intermediates III, when R4═H, R5 and R6(≠H) defined as above, are prepared according to the method described in Farmaco, Edizione Scientifica (1965), 20(6), 456-62: JP59204177, etc.;
Intermediates III, when R4≠H, are prepared from the intermediates (R4═H) according to the method described in WO2004093800A:




Wherein, X is halogen, methylsulfonyl or tosyl.
The preparation method of salts of the compounds having general formula I:
The preparation method of salts based on pyrimidinamine moiety:
The corresponding salts having general formula I-1 can be prepared by reaction of the compounds having general formula I with corresponding organic acids or inorganic acids, as shown in the following.




In addition, in general formula I, the salts can also formed based on nitrogen atom of pyrimidine ring, the preparation method refers to DE19647317, JP2001504473, U.S. Pat. No. 5,925,644, WO9822446 and ZA9710187, etc.
The reaction forming salts of compounds having general formula I-1 with organic acids or inorganic acids can be carried out at room temperature to boiling point of the solvent, normal temperature is from 20 to 100° C. The reaction time is in the range of 30 minutes to 20 hours, generally being 1-10 hours. The proper solvent mentioned may be selected from water, methanol, ethanol, isopropanol, benzene, toluene, xylene, acetone, ethyl methyl ketone, methyl isobutyl ketone, chloroform, dichloromethane, methyl acetate, ethyl acetate, tetrahydrofuran, 1,4-dioxane, DMF, N-methyl pyrrolidone or DMSO and so on.
The acids, which can be used to form salts with compounds having general formula I-1, includes hydrochloric acid, sulphuric acid, phosphorous acid, formic acid, acetic acid, trifluoroacetic acid, oxalic acid, methanesulfonic acid, p-toluenesulfonic acid, benzoic acid, phthalic acid, maleic acid, sorbic acid, malic acid or citric acid, etc. The further preferred acids are hydrochloric acid, sulphuric acid, phosphorous acid, trifluoroacetic acid, methanesulfonic acid or p-toluenesulfonic acid.
Although the compounds having general formula I and some compounds reported in prior art are both belong to substituted pyrimidines, there are still some obvious differences in structure between them. It is due to these differences in structure that lead to compounds of present invention with better fungicidal and/or insecticidal/acaricidal and antitumor activities.
The compounds of general formula I show excellent activity against both many plant pathogens/diseases in agricultural and other fields, and insects/mites, at the same time, they also have some antitumor activity. Therefore the technical scheme of the present invention also includes the uses of the compounds having general formula I or their salts to prepare fungicides, insecticides/acaricides in agricultural and other fields and to prepare antitumor agents in pharmaceutical fields.

(3) Determination of Acancidal Activity Against Carmine Spider Mite
Method: Broadbean shoots with two true leaves in pot were taken, the healthy adults of carmine spider mite were inoculated to the leaves. The adults were counted and then sprayed with airbrush at the pressure of 0.7 kg/cm2 and at dose of 0.5 ml. 3 replicates were set for each treatment. And then they were maintained in standard observation room. Scores were conducted and mortalities were calculated after 72 hrs.

Green peach aphids (Myzus Persicae Sulzer) were maintained on cabbage. Leaves (Diameter=3 cm) of approximately 15-30 aphids were put in the culture dishes. Bioactivity tests were used the method of Airbrush Foliar Spray, pressure=10 psi (0.7 kg/cm2), spray volume=0.5 mL. The studies were conducted at three constant temperatures 25±1 C. in incubator cabinets with 60±5% RH. Survey the survival aphids after 48 h and calculate the death rates.

Example 10
In Vitro Cell Inhibition Assay Against Human Cancer Cell T24 (Bladder Cancer Cell Line)
The tested compounds are dissolved in DMSO and diluted to designed concentration with culture medium.
The of cell culture technology in vitro was selected to evaluate growth inhibition rate against human bladder cancer cell line T24. 1000 to 3000 cells were inoculated into 24-well plate, followed by addition of cell culture medium (1 mL) known for technicans in this field (culture medium is RMPI-1640), after cells were cultured in incubator (CO2 5%, 37° C.) for 24 hours, then the tested compounds with designed concentration were added to each well. One thing should be paid much attention is that the culture medium volume, of tested compound does not exceed 0.5 of total volume. After incubation for one week, the culture medium was removed, the plate wells were washed with cold PBS once, fixed with 1% formalin at room temperature for 10 minutes, and washed with cold PBS one more time, followed by stain with 0.1% crystal violet for 30 minutes. Crystal violet can be recycled. The stained cells were washed with deionized water gently, dried in the air and reserved, were then incubated for 4 h. The inhibition rate was calculated according to the left cells of each treatment and contrast.
The inhibition rate=the left cells of each treatment/the left cells of contrast×100%
Part of the test results are as follows:
At the dose of 10 μM, the inhibition rate of compounds 5, 6 against bladder cancer cell line T24 was 100%.
