実験手順

A solution of 19.7 of phenylhydrazine (21.63 g) and 22 ml of 3-acetylpyridine (24.23 g) in glacial acetic acid (100 ml) is stirred and refluxed for 4.5 hours. The solution is cooled in an ice-water bath and neutralized with a saturated sodium bicarbonate solution (180 ml). The precipitate is collected, washed and dried to give 3-acetylpyridine phenylhydrazone.
