Embodiment 1
[0086] A specific synthetic route of an asymmetrically substituted 1,3,5-triazine compound is:
[0087]
[0088] Its concrete synthetic steps are as follows:
[0089] Add 13.5 mg of phenylisothiocyanate and 11.5 mg of tetramethylguanidine to 1 mL of dimethyl sulfoxide, then add 15.6 mg of benzamidine hydrochloride and rabbit hemoglobin (0.5 mol), and slowly add three times the amount tert-butyl hydroperoxide and reacted at 25°C (normal temperature) for ten minutes, and then detected the reaction progress by thin-layer chromatography; then added water to quench the reaction, extracted with ethyl acetate and added anhydrous sodium sulfate to dry , concentrated, followed by further purification by silica gel column chromatography (ethyl acetate / hexane) to obtain N 2 ,N 2 -Dimethyl-N 4 ,6-diphenyl-2,4-diamino-1,3,5-triazine 26.5 mg, yield 91%, white solid.
[0090] In this embodiment, the product is subjected to nuclear magnetic detection and analysis. For specific nuclear ...
Embodiment 2
[0093] A specific synthetic route of an asymmetrically substituted 1,3,5-triazine compound is:
[0094]
[0095] Its concrete synthetic steps are as follows:
[0096] Add 14.9 mg of 4-methylphenyl isothiocyanate and 11.5 mg of tetramethylguanidine into 1 mL of dimethyl sulfoxide, then add 15.6 mg of benzamidine hydrochloride and rabbit hemoglobin (0.5 mol), slowly drop After adding three times the amount of tert-butyl hydroperoxide, react at 25°C (normal temperature) for ten minutes, and then use thin-layer chromatography to detect the reaction progress; then add water to quench the reaction, extract with ethyl acetate and add anhydrous After drying over sodium sulfate, concentration, followed by further purification by silica gel column chromatography (ethyl acetate / hexane) to obtain N 2 ,N 2 -Dimethyl-N 4 -(p-Tolyl)-6-phenyl-2,4-diamino-1,3,5-triazine 27.5 mg, yield 90%, white solid.
[0097] In this example, the product is subjected to nuclear magnetic detection and an...
Embodiment 3
[0100] A specific synthetic route of an asymmetrically substituted 1,3,5-triazine compound is:
[0101]
[0102] Its concrete synthetic steps are as follows:
[0103] Add 14.9 mg of 3-methylphenyl isothiocyanate and 11.5 mg of tetramethylguanidine into 1 mL of dimethyl sulfoxide, then add 15.6 mg of benzamidine hydrochloride and rabbit hemoglobin (0.5 mol), slowly drop After adding three times the amount of tert-butyl hydroperoxide, react at 25°C (normal temperature) for ten minutes, and then use thin-layer chromatography to detect the reaction progress; then add water to quench the reaction, extract with ethyl acetate and add anhydrous After drying over sodium sulfate, concentration, followed by further purification by silica gel column chromatography (ethyl acetate / hexane) to obtain N 2 ,N 2 -Dimethyl-N 4 -(m-Tolyl)-6-phenyl-2,4-diamino-1,3,5-triazine 26.8mg, yield 88%, white solid.
[0104] In this example, the product is subjected to nuclear magnetic detection and a...
