実験手順

1-(Cyclopropylmethyl)-4-(2'-(4"-fluorophenyl)-2'-oxoethyl)piperidine (Example 429, 1.0 g, 3.6 mmol) was mixed with dry tetrahydrofuran (10 mL). A solution of phenyl magnesium bromide in ether (3.0 M, 3 mL, 9 mmol) was added with stirring. The reaction mixture was stirred for 24 h; poured onto a saturated NH4Cl solution and extracted with ethyl acetate three times. The combined organic layers were dried over magnesium sulfate and filtered. Solvent was removed in vacuo. Trituration with ether-hexanes (1:9) and filtration afforded the title compound, a solid, which was dried in vacuo (0.9 g). mp 115°-116° C.; Anal. : Calcd for C23H28FNO: C, 77.36, H, 7.90, N, 3.92, F, 5.32; Found: C, 77.47, 77.41, H, 8.00, 7.92, N, 3.42, 3.52, F, 5.09.
