Reaktionsschritte

Following the synthetic procedure outlined in Step 3 of Example 1, 250 mg (0.93 mmol) of 1-(2-bromocyclopenten-1yl)-4-(methylthio) benzene (Example 1, Step 2) was reacted with 290 mg (1.9 mmol) of 4-hydroxymethylphenylboronic acid (Step 1). Purification by silica gel chromatography (MPLC) with ethyl acetate/hexane (1:4) gave 255 mg (92%) of 1-[2-(4-hydroxymethylphenyl)cyclopenten-1-yl]-4-(methylthio)benzene as a solid: mp 82°-85° C; NMR (CDCl3) d 2.04 (m, J=7 Hz, 2H), 2.45 (s, 3H), 2.88 (t, J=7 Hz, 4H), 4.64 (s, 2H), 7.08 (s, 4H), (m, 2H), 7.15-7.25 (m, 4H).
