A solution of 3-Chloro-6-(2-cyclohex-1-enyl-ethyl)-6-cyclopentyl-4-hydroxy-5,6-dihydro-pyran-2-one (150 mg, 0.46 mmol, from Step 1 below), 5-Pyridin-4-yl-4H-[1,2,4]triazole-3-thiol (82 mg, 0.46 mmol), and triethylamine (64 □L, 0.46 mmol) dissolved in DMF (5 mL) was heated to 55° C. under N2 for 8 h. The resulting mixture was concentrated and purified by Prep HPLC to give the title compound (58 mg, 27%) as a pale yellow solid. 1H NMR (DMSO-d6): δ 1.62-1.82 (m, 12H), 2.03-2.11 (m, 8H), 2.51 (m, 1H), 2.87 (d, 1H, J=17.5 Hz), 3.11 (d, 1H, J=17.5 Hz), 5.55 (s, 1H), 8.01 (d, 2H, J=5.8 Hz), 8.84 (d, 2H, J=5.8 Hz). ESIMS: MH+ 467.15
