Procedure
DBU (55 ul, 0.367 mmol) was added to a solution of 6-[2-(3-chloro-4-methoxyphenyl)ethyl]-6-cyclopentyldihydro-2H-pyran-2,4(3H)-dione (58.6 mg, 0.167 mmol) in benzene (16.0 ml) and acetonitrile (3 ml), under an atmosphere of argon. 3-(chloromethyl)pyridine hydrochloride (27.4 mg, 0.167 mmol) was then added. The reaction mixture was stirred at room temperature for 24 hrs, after which time the mixture was filtered through a plug of Celite. The filtrate was concentrated in vacuo and the residue purified by prep HPLC to afford the title compound as a white solid (8.60 mg). 1H NMR (CDCl3): δ 1.40-1.80 (bm, 8H), 1.90 (m, 2H), 2.30 (m, 1H), 2.51 (m, 3H), 2.74 (d, J=17.27 Hz, 1H), 3.74 (m, 3H), 3.85 (s, 3H), 6.73 (d, J=8.32 Hz, 1H), 6.89 (m, 1H), 7.02 (s, 1H), 7.30 (m, 1H), 7.92 (m, 1H), 8.26 (s, 1H), 8.55 (s, 1H).
