Reaction Conditions:
in toluene at 60; for 5 h;Time;
Steps:
3.4 4. Preparation of 565 4-[(4,6-dioctylthio-1,3,5-triazin-2-yl)amino]-2,6-di-tert-butylphenol
To the reaction solution of the compound II, 120 ml of toluene (the toluene layer after solvent removal in the preparation of the compound III) was added at 25 ° C,The compound III produced in the step 2 is added dropwise, after the addition is completed,After heating to 60 ° C and reacting for 5 hours, the final product was produced, and the content of the sample was 98.21%. The final product was allowed to stand for stratification, and the organic layer was taken out, washed twice with water, and desolvated under reduced pressure.Crystallization was carried out by adding 250 ml of methanol, and the mixture was filtered and dried to give 42.0 g.
