Versuchsvorschrift

A mixture of 32.4 g. of 2-aminomethylpyridine and 96 ml. of 97% formic acid is heated under reflux for 3.5 hrs. The resulting solution is subjected to vacuum distillation, the desired product, 2-formamidomethylpyridine, being isolated as a yellow oil crystallizes to a solid having a melting point at about room temperature.
