실험 절차

In 100 ml of xylene were dissolved 37.0 g (93.9 mmols) of crude 2-(5-chloro-2H-benzotriazole-2-yl)-4-(2-hydroxyethyl)-6-(N,N-diethylaminomethyl)phenol synthesized in Example 10 and 27.2 g (93.9 mmols) of the purified product of 2-(5-chloro-2H-benzotriazole-2-yl)-4-(2-hydroxyethyl)phenol synthesized in Example 7. 5 ml of methanol solution of 28% sodium methylate was added, and the mixture was refluxed in a nitrogen stream for 10 hours. The subsequent treatment was carried out in the same manner as in Example 12, giving 30.8 g of 2,2'-methylenebis[6-(5-chloro-2H-benzotriazole-2-yl)-4-(2-hydroxyethyl)phenol] as pale yellow crystals (yield 55.0%, purity 99.0%).
