Reaction Steps
In 25 ml of n-butanol were dissolved 25.5 g (0.1 mols) of the purified product of 2-(2H-benzotriazole-2-yl)-4-(2-hydroxyethyl)phenol synthesized in Example 6, 5.2 g of 80% paraformaldehyde and 11.0 g (0.15 mols) of diethylamine. The solution was refluxed with heating at 105° C. for 24 hours. After completion of the reaction, the solvent and remaining raw materials were collected under reduced pressure, giving 34.7 g of objective 2-(2H-benzotriazole-2-yl)-4-(2-hydroxyethyl)-6-(N,N-diethylaminomethyl)phenol as a brown oil (yield 98.9%, purity 96.9%).
