A 0.06 gram (0.0004 mole) sample of 4-chlorophenylisocyanate was weighed into a two-dram vial, followed in turn by 1.2 mL of methylene chloride, 0.18 gram (0.0004 mole) of {1-[(4-(2-pyridyloxy)phenyl)methyl](4-piperidyl)}[4-(trifluoromethyl)phenyl]methanol, and 0.06 mL of triethylamine. The vial was tightly capped and gently shaken at 35° C. for 16 hours using a vortex mixer. After this time, the methylene chloride was removed under a nitrogen stream to provide a residue. The residue was purified with column chromatography on silica gel using mixtures of acetone and methylene chloride as eluants. The appropriate fractions were combined and concentrated under reduced pressure, yielding 0.2 gram of Compound 227. The NMR spectrum was consistent with the proposed structure.
