Procedure

A concentrated hydrochloric acid was added to a mixture of cyclooctanone (3.84 g, 30.43 mmol) and butylamine (3.01 mL, 30.43 mmol) by two drops, and the mixture was stirred at room temperature for 15 hours. Diluted sodium carbonate aqueous solution and ethyl acetate were added in the reaction mixture to separate the mixture, and the organic layer was washed with water and saturated saline. After the organic layer had been dried, the solvent was removed by distillation and 4.72 g of colorless oily matter was obtained (86%). This imine (4.67 g, 25.76 mmol) was reacted as mentioned above together with trimethylmethane tricarboxylic acid (3.42 g, 18 mM) in trigrim (40 mL), and viscous yellow oily matter (AA17, 2.62 g, 47%) was obtained.
