Procedure
The title compound was prepared by General Method 3. A solution of 1-(2-cyclohexylethyl)-1-p-tolylhydrazine (0.15 g) in water (1 mL) and conc. HCl (0.18 mL) was heated to 60° C. EtOH (1 mL) was added followed by 4,4-diethoxy-N-methylbutan-1-amine (0.12 g) and the temperature was raised to 90° C. Conc. HCl (0.1 mL) was added and the heating was continued for an additional 6 h after which the reaction mixture was cooled and stirred at 25° C. for 12 h. The reaction mixture was concentrated under reduced pressure and the residue was purified by silica gel chromatography (eluent EtOAc/EtOH/NH3: 9/1/0.1) to obtain 79 mg of product.
