実験手順

To a solution of 2-chloro-5-nitrophenylhydrazine (37.60 g) in dichloromethane (200 ml), triethylamine (22.27 g) and pivaloyl chloride (26.59 g) were added, and the resultant mixture was stirred at room temperature for 12 hours. The reaction mixture was combined with water. The dichloromethane layer was washed with water, dried and concentrated under reduced pressure to give 1-(2-chloro-5-nitrophenyl)-2-(2,2-dimethylpropionyl)hydrazine (42.23 g). m.p., 153.3° C.
