1-BENZYL-1H-BENZOTRIAZOLE Use and Manufacturing
General procedure: To the mixture of benzotriazole 10mmol and 40mmol sodium hydroxide, 8-10mLN, N-dimethylformamide was added. Corresponding 10mmol of alkyl halides were added and stirred for 30min [21, 22]. The mixture was washed with water. 1- and 2-alkyl substituted derivatives were separated using column chromatography (Silica gel 200-400, Petroleum ether: Chloroform, 80:20).(Phenylmethyl)-1H-benzotriazole (Phenylmethyl)-1H-benzotriazole was prepared from 1H-benzotriazole (11.91 g, 0.100 mol) and benzyl chloride as in for 1 hour to give the title compound and (phenylmethyl)-2H-benzotriazole in a ratio of 75:25. Workup and two recrystallizations gives the pure 1H-isomer: mp 117-119 C. (CH3 CN); (lit.1 mp 114-117 C.; lit.2, 3 mp 115-116 C.). 1 Claramunt, R. M.; Elguero, J.; Garceran, R.
