3-Cyanobenzamide → 3-Cyanobenzoic acid

Participants

Reaction Steps

Sodium nitrite (2.07 g) was dissolved in a 70 wt. % aqueous sulfuric acid solution (100 ml), and m-cyanobenzamide (2.92 g) was added to the resultant solution. The mixture was allowed to react at 40° C. for one hour with stirring. The precipitated crystals were collected through filtration, washed with water, and dried, to thereby obtain 2.68 g of m-cyanobenzoic acid (yield 92%). The m-cyanobenzoic acid obtained had a purity of 99% or more.
