Following the synthetic procedure outlined in Step 3 of Example 1, 500 mg (1.9 mmol) of 1-(2-bromocyclopenten-1-yl)-4-(methylthio) benzene (Example 1, Step 2) was reacted with 590 mg (3.8 mmol) of 4-fluoro-2-methylphenylboronic acid (Step 1). Purification by silica gel chromatography (MPLC) with hexane gave 500 mg (95%) of 1-[2-(4-fluoro-2-methylphenyl)cyclopenten-1-yl]-4-(methylthio)benzene as a colorless solid: mp 67°-68° C.; NMR (CDCl3) d 2.00-2.11 (m, 2H), 2.05 (s, 3H), 2.41 (s, 3H), 2.69-2.77 (m, 2H), 2.86-2.95 (m, 2H), 6.80-7.07 (m, 7H) .
