Reaction Steps
A mixture of 2.3 g of 5-trifluoromethyl-2-(2,4-dihydroxyphenyl)-2H-benzotriazole prepared in Example 31, 1.3 mL of butyl glycidyl ether and 100 mg of ethyl triphenylphosphonium bromide in 50 mL of xylene is heated to reflux under nitrogen for 14 hours. Water (25 mL) and 25 mL of ethyl acetate are added and 3 g of the crude product is isolated. Recrystallization from heptane give 2.1 g of the title compound whose structure is confirmed by nmr.
