Reaction Steps

A stirred mixture of 2,4-bis(4-tert-butylphenyl)-6-(2,4-dihydroxy-5-hexylphenyl)-1,3,5-triazine, 5 g of 1-iodooctane, 1 g of Aliquat® 336 (tricaprylmethylammonium chloride), 14 g anhydrous potassium carbonate, and 200 mL methyl isobutyl ketone (MIBK) was heated at 115-120° C. for 5 hr, and then allowed to cool to room temperature. The mixture was extracted with methylene chloride and the combined methylene chloride extracts were concentrated under reduced pressure. The resulting semi-solid residue was recrystallized from acetone to give 12 g of 2,4-bis(4-tert-butylphenyl)-6-(2-hydroxy-4-octyloxy-5-hexylphenyl)-1,3,5-triazine as a yellow solid in 97% purity as determined by HPLC (area % at 290 nm). A second recrystallization from acetone yielded an analytical sample (100% purity by HPLC).
