Procedure

A mixture of 6.5 g of 5-chloro-2-(2,4-dihydroxyphenyl)-2H-benzotriazole, 7.1 g of 1-bromooctane, 5.2 g of anhydrous potassium carbonate and 100 mL of acetone is refluxed for 24 hours. To the resulting mixture, about 100 mL of water and ethyl acetate are added, and petroleum eg of crude product is isolated. Column chromatography using petroleum ether yields 0.9 g of the title compound whose structure is confirmed by Hnmr and mass spectrometry.
