実験手順

N'-t-butyl-N-benzoylhydrazine (1.0 g,) in 2 ml toluene was added dropwise to a solution of beta-trifluoromethylcrotonyl chloride (prepared by addition of oxalyl chloride (1.3 g) to a solution of 1.5 g beta-trifluoromethylcrotonic acid in 5 ml toluene at 23° C.). After 30 minutes at 23° C., the reaction mixture was partitioned between saturated aqueous sodium bicarbonate (20 ml) and ether (20 ml). The ether layer was evaporated under reduced pressure to about 10 ml and the excess hydrazine was removed by filtration. The filtrate was evaporated to give N'-t-butyl-N-benzoyl-N'-(beta-trifluoromethylcrotonyl)hydrazine as a colorless oil.
