    その他Purification by silica gel chromatography (MPLC) with hexane

実験手順

Following the synthetic procedure outlined in Step 3 of Example 1, 240 mg (0.89 mmol) of 1-(2-bromocyclopenten-1-yl)-4-(methylthio) benzene (Example 1, Step 2) was reacted with 360 mg (1.8 mmol) of 4-trifluoromethylphenylboronic acid (Step 1). Purification by silica gel chromatography (MPLC) with hexane gave 240 mg (81%) of 1-[2-(4-trifluoromethylphenyl)cyclopenten-1-yl]-4-(methylthio)benzene as a colorless solid: mp 60.0°-61.5° C.; NMR (CDCl3) d 2.06 (m, J=7 Hz, 2H), 2.46 (s, 3H), 2.89 (t, J=7 Hz, 4H), 7.06 (d, J=6 Hz, 2H), 7.10 (d, J=Hz, 2H), 7.27 (d, J=8 Hz, 2H), 7.46 (d, J=8 Hz, 2H).
