Synthesis

32046-62-1
The general procedure for the synthesis of 5-bromo-1H-benzotriazole from 4-bromo-o-phenylenediamine was as follows: 4-bromobenzene-1,2-diamine (10 g, 53.5 mmol) was dissolved in a mixture of acetic acid (20 ml, 349 mmol) and water (100 ml) in an ice-bath at 0-5 °C. A solution of sodium nitrite (4.06 g, 58.8 mmol) in water (10 ml) was added slowly and dropwise. The ice bath condition was maintained and the reaction mixture was stirred for 1 hour. Subsequently, additional acetic acid (20 ml, 349 mmol) was added and the reaction system was heated to 80-85°C and stirring was continued for 1 hour. Upon completion of the reaction, the hot solution was filtered to remove insoluble black impurities. The filtrate was cooled to 0-5 °C and left to age for 30 min. The precipitate precipitated was washed with water and dried under vacuum at 45 °C to afford the target product 5-bromo-1H-benzotriazole in a yield of 9.48 g (90% yield).
