(6E)-6-[(4-chlorophenyl)methylidene]-2,2-dimethylcyclohexan-1-one

Conditions: temp:45.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2-(4-Chlorobenzylidene)-6-methylcyclohexanone (7.0 g), prepared above, and then methyl iodide (5.1 g) are added successively to a reaction medium prepared from toluene (25 cc), tert-amyl alcohol (3.6 cc) and sodium hydride (1.35 g of 60% strength dispersion in oil) and heated to 45° C. The mixture is brought to reflux (1 h), poured into water and extracted with ethyl acetate. After drying and concentration, the residue is recrystallized in methanol to give 2-(4-chlorobenzylidene)-6,6-dimethylcyclohexanone (4.7 g), m.p. 92°. are added successively to a reaction medium to reflux (1 h) extracted with ethyl acetate After drying concentration the residue is recrystallized in methanol
