Under nitrogen, a stirred solution of 79 mg (0.24 mmol) of 1-[2-(4-hydroxymethylphenyl)cyclopenten-1-yl]-4-(methylsulfonyl)benzene (Example 9) in 2 mL of dry THF at 0° C. was treated with 15 mg (0.6 mmol) of sodium hydride (95%); after 30 minutes, 0.1 mL (1.6 mmol) of methyl iodide was added and the reaction was allowed to warm to ambient temperature overnight. The solvent was removed in vacuo; the residue was dissolved in ethyl acetate and washed with water, dried (MgSO4), and reconcentrated. Purification by silica gel chromatography (MPLC) with hexane/ethyl acetate (5:1) and subsequent lyophilization from acetonitrile/water (1:1) gave 25 mg (30%) of 1-[2-(4-methoxymethyl phenyl)cyclopenten-1-yl]-4 -(methylsulfonyl)benzene as a colorless solid: NMR (CDCl3) d 2.09 (m, J=7 Hz, 2H) , 2.92 (t, J=7 Hz, 4H) , 3.03 (s, 3H) , 3.40 (s, 3H), 4.42 (s, 2H), 7.12 (d, J=8 Hz, 2H), 7.20 (d, J=8 Hz, 2H) , 7.33 (d, J=8 Hz, 2H) , 7.73 (d, J=8 Hz, 2H; MS (EI) m/e (rel intensity) 342 (100), 81 (27), 69 (62).
