Reaction Conditions

Reaction Steps

50 mg of (piperidin-4-yl) 2-cyclobutyl-2-hydroxy-2-phenylacetate hydrochloride, 25 mg of 5-bromo-2-methyl-2-pentene, 25 mg of potassium iodide and 47 mg of anhydrous potassium carbonate were suspended in 5 ml of anhydrous N,N-dimethylformamide, and this suspension was stirred at 70° C. for 3 hours. The reaction mixture was cooled to room temperature, mixed with water, and then extracted with diethyl ether. The organic layer was washed with a saturated aqueous solution of sodium chloride and then dried over anhydrous magnesium sulfate. After the solvent was distilled off under reduced pressure, the resulting residue was purified by silica gel column chromatography (developing solvent: chloroform/methanol=20/1) to obtain 35 mg of the title compound.
