実験手順

In a separate reaction vessel, a solution of 0.5 gram (0.0012 mole) of 4-[bis(4-trifluoromethoxyphenyl)hydroxymethyl]piperidine (prepared in Step B of Example 7) and 0.09 gram (0.0012 mole) of pyridine in a small amount of tetrahydrofuran was stirred, and the solution of 3-chloro-4-methoxybenzoyl chloride in tetrahydrofuran, prepared above, was added. Upon completion of addition, the reaction mixture was stirred at ambient temperature for about 15 minutes and then filtered to remove a white solid. The filtrate was stirred for about 18 hours and then was partitioned between ethyl acetate and an aqueous solution saturated with sodium chloride. The organic layer was separated and passed through a column of silica gel. Elution was accomplished with 50% ethyl acetate in hexane. The product-containing fractions were combined and concentrated under reduced pressure, yielding 0.62 gram of N-(3-chloro-4-methoxyphenylcarbonyl)-4-[bis(4-trifluoromethoxyphenyl)hydroxymethyl]piperidine. The NMR spectrum was consistent with the proposed structure.
