Reaction Steps

A stirred mixture of 1.0 gram (0.002 mole) of N-[4-(cyclopropylmethoxy)phenylmethyl]-4-[bis(4-trifluoromethylphenyl)hydroxy-methyl]piperidine N-oxide, 0.3 gram (0.002 mole) of ethyl iodide, and about 5.0 mL of acetonitrile was heated at reflux for several hours. The reaction mixture was then cooled to 0° C., and petroleum ether was added. Upon completion of the addition the mixture was filtered and the filtrate was concentrated under reduced pressure, yielding 0.6 gram of N-[4-(cyclopropylmethoxy)phenylmethyl]-N-ethoxy-4-[bis(4-trifluoromethylphenyl)hydroxymethyl]-piperidinium iodide. The NMR spectrum was consistent with the proposed structure.
