This compound was prepared according to the procedure of Example 1. A mixture of 4.6 g (0.015 mole) of α,α-bis-(p-fluorophenyl)-4-piperidinemethanol, 2.2 g (0.015 mole) of 5-(chloromethyl)-3-methyl-2-oxazolidinone, 5.3 g (0.05 mole) of anhydrous sodium carbonate and 0.4 g of potassium iodide in 100 ml of 1-butanol gave a gum as residue. The gum was purified by column chromatography on 50 g of Florisil®. Fractions eluted with 5-20% acetone in benzene were combined and concentrated to give a solid residue. The solid was recrystallized from isopropyl ether-2-propanol to yield 1.5 g (24%) of white solid, m.p. 147°-148° C.
