Reaction Steps
A mixture of methanol 60 ml, water 30 ml, 97% sodium hydroxide 12.4 g and 2-nitro-2'-hydroxy-5'-methylazobenzene 12.9 g was heated and stirred at 45°~50° C. 9-fluorenone 1.0 g and then glucose 5.5 g were added to the resultant mixture over 30 minutes while stirring. The mixture was further stirred at 75° C. (boiling point) for 7 hours. As this result, the azobenzene disappeared to produce 2-(2'-hydroxy-5'-methylphenyl)benzotriazole-N-oxide.
