Versuchsvorschrift

A compound having general Formula 3, exemplified by 6-Isopropyl-3-methyl-2-{4-[(4-propoxy-benzylidene)-amino]-benzylidene}-cyclohexanone (Compound 3; FIG. 1) can be prepared as follows. A solution of menthone (154 mg, 1.0 mmol) and 4-aminobenzaldehyde (121 mg, 1.0 mmol) in dimethylsulfoxide is treated with potassium hydroxide (56 mg, 1.0 mmol). The reaction is stirred until no futher reaction occurs. The reaction mixture is poured into ethyl acetate and water. The organic phase is collected, dried and concentrated to give 2-(4-Amino-benzylidene)-6-isopropyl-3-methyl-cyclohexanone. The 2-(4-Amino-benzylidene)-6-isopropyl-3-methyl-cyclohexanone is dissolved in dichloromethane and treated with 4-propoxybenzaldehyde (164 mg, 1.0 mmol) and anhydrous Na2SO4. The reaction mixture is stirred until no further reaction occurs. The reaction mixture is filtered and concentrated to give the title compound.
