Reaction Steps

In a 1 liter Paar hydrogenator is added 3.0 grams of 5,6-dimethyl-7-nitrobenzotriazole in 250 milliliters of absolute ethanol along with 0.5 gram of 5% Pd/C. Hydrogen is introduced at about 40 psi and the reduction is accomplished without heating. The catalyst is removed by filtration and on evaporation of the solvent, 2.5 grams (94%) of the product is isolated, m.p. 114°-117° C. The analytical sample is recrystallized from n-hexane, m.p. 116°-120° C.
