Versuchsvorschrift

1,3-Diacetoxymethyl-5-[2-[1-(formylmethyl)cyclohexyl]ethoxy]benzene (synthesized in Example 32) (215 mg) and 4-(p-toluidino)piperidine (synthesized in Preparation Example 4-5) (127 mg) were dissolved in 1,2-dichloroethane (5 mL). To this was added acetic acid (0.04 mL) at room temperature. The solution was stirred for 45 minutes. Sodium triacetoxyborohydride (294 mg) was added to the solution at room temperature. The solution was stirred for 3 hours. saturated aqueous sodium bicarbonate solution was added to the solution and it was extracted with chloroform. The organic layer was dried over anhydrous magnesium sulfate, and filtered. The filtrate was then concentrated under reduced pressure. The resulting residue was purified by chromatography [silica gel, chloroform-methanol (10:1)] to give the title compound (334 mg). This product was subjected to the subsequent step without further purification.
