Mode opératoire

A mixture of 5 gm 2-(2,4-dihydroxyphenyl)-4,6-bis(4-phenoxyphenyl)-1,3,5-triazine, 2.5 gm 1-iodooctane, 6.6 gm anhydrous potassium carbonate, 0.5 gm Aliquat 336 and 25 ml MIBK was heated to reflux for 3 hr. The reaction mixture was cooled to room temperature, diluted with methylene chloride, filtered through Celite. The filtrate was concentrated under reduced pressure. The residue thus obtained was passed through a silica gel column. The material thus obtained was crystallized with acetone to give 3.5 gm of pure 2-(2-hydroxy-4-octyloxyphenyl)-4,6-bis(4-phenoxyphenyl)-1,3,5-triazine.
