A nucleophilic substitution of the chlorine atom in 2,4-dinitro-1-chlorobenzene with some pyrazole derivatives followed by selective reduction of the substitution products thus formed and diazotization of the resulting monoamine compounds provides benzotriazoles of 3-methyl-5- pyrazolyl- and 3-methyl-4- pyrazolyl- genii. Industrially advantageous azocompouns based thereon have been also synthesized.
