Procedure

In 50 ml of ethanol was dissolved 3 g of cyclooctylamine. To the solution was added 11.41 g of 2-[bis-(4-benzyloxyphenyl)methyl]benzaldehyde obtained by Reference Example 8, and the mixture was heated under reflux for 2 hours. Thereafter, 1.78 g of sodium borohydride was added thereto, and the mixture was heated under reflux for 2 hours. The solvent was evaporated-under reduced pressure, and water was added to the residue. The aqueous mixture was extracted with ether, and the organic layer was separated. The aqueous layer was extracted with ether, and then the organic layers were combined and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was recrystallized to afford 9.19 g of the desired product (Compound 82).
