Examples
Embodiment 1
[0040] Example 1: Synthesis of 2,4-dimethyl-6-[4-(N,N-di-p-tolyl)-anilinoethyl]-s-triazine (1)
[0041] Weigh 1 molar amount of 1,3,5-trimethyl-s-triazine and 0.6 molar amount of potassium hydroxide, then add 6 L of methanol to dissolve. At the reflux temperature, 3 L of methanol solution of 1 molar amount of 4-(N,N-xylanilino)benzaldehyde was dripped dropwise into the flask. Solvent, the residue was separated by silica gel column chromatography with V(toluene):V(ethanol)=10:1 toluene-ethanol mixture as eluent to obtain a pale yellow product. Yield 41.3%, mass spectrum m / z: 406.1 (M + ). 2,4-Dimethyl-6-[4-(N,N-di-p-tolyl)-anilinoethyl]-s-triazine (1) has an exact molecular mass of 406.22, which was measured by a mass spectrometer in this embodiment The molecular mass is 406.1, indicating that the compound (1) obtained in Example 1 is correct.
Embodiment 2
[0042] Example 2: Synthesis of 2-methyl-4,6-bis[4-(N,N-di-p-tolyl)-anilinoethyl]-s-triazine (2)
[0043] Weigh 1,3,5-trimethyl-s-triazine, 1.2 moles of potassium hydroxide, and 2 moles of 4-(N,N-dimethylanilino)benzaldehyde, then add methanol 20L dissolve. Reflux for 12 hours, remove the solvent with a rotary evaporator, and use a V(toluene):V(ethanol)=10:1 toluene-ethanol mixture as the eluent to separate the residue through silica gel column chromatography to obtain a pale yellow product. Yield 38.6%, m / z: 690.3 (M+H) + ; 2-methyl-4,6-bis[4-(N,N-di-p-tolyl)-anilinoethyl]-s-triazine (2) exact molecular mass is 689.35), measured m / z: 690.3( M+H) + , indicating that the obtained compound (2) is correct.
Embodiment 3
[0044] Example 3: Synthesis of 2,4,6-three [4-(N,N-di-p-tolyl)-anilinoethyl]-s-triazine (3)
[0045] Weigh 6 moles of 4-(N,N-xylanilino)benzaldehyde and 1.8 moles of potassium hydroxide, then add 20 L of methanol to dissolve. 5 L of 1,3,5-trimethyl-s-triazine solution in which 1 mole was dissolved was dropped dropwise into the flask. Toluene): V (ethanol)=10:1 toluene-ethanol mixture as eluent, separated by silica gel column chromatography to obtain light yellow product. Yield 43.7%, m / z: 973.5 (M+H) + . The exact molecular mass of 2,4,6-tris[4-(N,N-xylyl)-anilinoethyl]-s-triazine (3) is 972.49, measured m / z: 973.5 (M+H) + , illustrates that the compound (3) obtained in Example 3 is correct.
