Participants

Reaction Steps

In 100 ml of xylene were dissolved 35.9 g (97.0 mmols) of crude 2-(2H-benzotriazole-2-yl)-4-(3-hydroxypropyl)-6-(N,N-diethylaminomethyl)phenol synthesized in Example 11 and 26.1 g (97.0 mmols) of the purified product of 2-(2H-benzotriazole-2-yl)-4-(3-hydroxypropyl)phenol synthesized in Example 6. 5 ml of a 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 33.0 g of 2,2'-methylenebis[6-(2H-benzotriazole-2-yl)-4-(3-hydroxypropyl)phenol] as white crystals (yield 61.2%, purity 99.0%).
