Dimethylformamide → 2-Cyanomethyl-5-methylbenzamide

Participants

Reaction Steps

2-Cyanomethyl-5-methylbenzoic acid (16.3 g) and dimethylformamide (0.1 mL) were suspended in tetrahydrofuran (160 mL), and oxalyl dichloride (12.2 mL) was added dropwise under ice-cooling. After cease of foaming, the solvent was evaporated. The obtained residue was dissolved in tetrahydrofuran, and the solution was added dropwise to 28% aqueous ammonia solution under ice-cooling. After the completion of the reaction, the solvent was evaporated, and the precipitated crystals were collected by filtration to give 2-cyanomethyl-5-methylbenzamide (10.9 g).
