The paper investigates the HCl concentration impact on the main and by-processes during the reduction of 1-(2-nitroaryl)-1H-benzotriazole by tin (II) chloride in acidic aqueous-alcoholic medium. The authors have observed the formation of azoxy compounds in addition to the target amino derivative at low HCl content in the reaction mass. The use of 36% hydrochloric acid causes the alkylation of the formed amino compound with alcohol as a solvent.
