実験手順
5-Methoxycarbonyl2-[2-hydroxy-3-(4-chloro-α,α-dimethylbenzyl)-5-tert-butylphenyl]-2H-benzotriazole (3.89 g, 0.0081 mol) and 1-(2-hydroxy-2-methylpropoxy)-2,2,6,6-tetramethyl-4-hydroxypiperidine (2.41 g, 0.0098 mol) are reacted together according to the procedure of Example 1. The title compound is obtained in a yield of 2.26 g (40.2%) as a yellow solid, melting at 80-90° C., whose structure is consistent with 1Hnmr and mass spectrometry. The compound has a molar absorptivity of 17,411 l/mole cm.
