反応手順

This compound was prepared in a manner analogous to that of Step D of Example 4, with 0.3 gram (0.001 mole) of 4-(2-methyl-2H-tetrazol-5-yl)phenylmethyl bromide, 0.5 gram (0.001 mole) of 4-[bis(4-trifluoromethoxyphenyl)hydroxymethyl]piperidine (prepared as in Step C of Example 4), and 0.6 gram (0.004 mole) of N, N-diisopropylethylamine in about 5 mL of dimethyl sulfoxide as reagents. The crude reaction product was subjected to column chromatography on silica gel, with 3:7 acetone:methylene chloride as the eluant. The product-containing fractions were combined and concentrated under reduced pressure, yielding about 0.2 gram of N-[4-(2-methyl-2H-tetrazol-5-yl)phenylmethyl]-4-[bis(4-trifluoromethoxyphenyl)hydroxymethyl]piperidine. The NMR spectrum was consistent with the proposed structure.
