反応手順
In a manner similar to that described for Example 6B, 1-{4-[1-acetyl-4-(4-hydroxy-3-methylphenyl)-piperidin-4-yl]-2-methylphenoxy)-3,3-dimethylbutan-2-one was prepared by using 1 equiv of 1-chloropinacolone and cesium carbonate. 1-{4-[1-Acetyl-4-(4-hydroxy-3-methylphenyl)-piperidin-4-yl]-2-methylphenoxy}-3,3-dimethylbutan-2-one was then alkylated with (S)-glycidol as in Example 1H to yield 1-(4-(1-acetyl-4-[4-(2,3-dihydroxypropoxy)-3-methylphenyl]-piperidin-4-yl}-2-methylphenoxy)-3,3-dimethylbutan-2-one.
