Procedure
A solution of 3-(1-methylethyl)-5-(trichloromethyl)-1,2,4-oxadiazole (prepared as in Example 158, Alternative synthesis, Step 3, 179 g, 0.78 mol) in MeOH (300 mL) was treated with 4-piperidinemethanol (108 g, 0.94 mol) and stirred and heated at 50° C. overnight. The solvent was removed and the residue was purified by flash chromatography on a silica gel column to give {1-[3-(1-methylethyl)-1,2,4-oxadiazol-5-yl]-4-piperidinyl}methanol (60 g, 34%) as a pale yellow oil.
