실험 절차
To a stirring mixture of 1 eq of cyanuric chloride, 3 eq of AlCl3, and 1.9 eq of m-xylene in chlorobenzene, was added 13% (based on the weight of cyanuric chloride) of concentrated HCl at ice-bath temperature. Within 30 min at room temperature, 97% of the cyanuric chloride had reacted, to produce 2-chloro-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine and 2,4,6-tris(2,4-dimethylphenyl)-1,3,5-triazine in a ratio of 96:4; no side products were detected. Further stirring gave 99.5% cyanuric chloride conversion, with the ratio of 2-chloro-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine to 2,4,6-tris(2,4-dimethylphenyl)-1,3,5-triazine unchanged and no other products were detected. Thereafter, the reaction mixture was allowed to react with 1.1 eq of resorcinol at 85° C. for 1.5 h. HPLC analysis of the reaction mixture showed the formation of 92.7% 2-(2,4-dihydroxyphenyl)-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine, 5% 2,4,6-tris(2,4-dimethylphenyl)-1,3,5-triazine, and 2.3% unreacted 2-chloro-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine.
