실험 절차

A solution of 0.52 g (3.0 mmol) of 2,5-dimethylbenzoylacetonitrile, 0.45 g (3.0 mmol) of trimethylorthobutyrate and 0.632 g (0.58 mL, 6.2 mmol) of acetic anhydride in 5.0 mL of ethyl acetate was refluxed overnight and then cooled. The solvents were removed in vacuo and the residues were dissolved in 10 mL of ethanol. One-half of this solution, containing 1.5 mmol of 1-cyano-1-(2,5-dimethylbenzoyl)-3-methoxy-1-pentene was mixed with 0.7 mL (0.51 g, 5.0 mmol) of triethylamine and 0.37 g (1.50 mmol) of 2,6-dichloro-4-trifluoromethylphenylhydrazine and refluxed for 2.5 hours. The reaction mixture was cooled and partitioned between dilute hydrogen chloride and ethyl acetate. The organic phase was washed with water and then dried with brine and with magnesium sulfate. The solvent was evaporated to give an oil which was chromatographed on silica gel by the flash method eluting with 4:1 hexane/ethyl acetate to give the title compound as an amorphous foam.
