実験手順

A stirred suspension of 2,2′-dimethoxybenzophenone (20.72 g, 0.0855 mol) and 20 mL (0.412 mol) of hydrazine monohydrate in 25 mL of 1-butanol was heated to reflux overnight. After cooling to room temperature the two phase reaction mixture was poured into water and cooled to induce crystallization. The white precipitate was filtered, washed with water and petroleum ether and dried in vacuo to yield 2,2′-dimethoxybenzophenone hydrazone (1).
