実験手順
1-Methyl-5-nitrobenzotriazole (0.7 g) was reduced by SnCl2 (4.0 g) at 0° C. in 5 mL of conc. HCl. The pH of the reaction mixture was adjusted to basic and the mixture was extracted with EtOAc. The product 5-amino-1-methylbenzotriazole (0.4 g) obtained after removal of the solvent was used for the next reaction without further purification.
後処理
