Reaction Steps
A solution of 6-but-3-ynyl-3-chloro-6-cyclopentyl-dihydro-pyran-2,4-dione (200 mg, 0.66 mmol) from Step 4 above, 3-iodophenol (145 mg, 0.66 mmol), bis(triphenylphosphine)palladium (II) dichloride (18 mg, 0.026 mmol), and copper (I) iodide (10 mg, 0.052 mmol) in DMF (0.66 mL) and diisopropylamine (0.66 mL) was sonicated for 1 minute and then heated to 90° C. for 20 minutes. The reaction was cooled to room temperature, and then diluted with 10 mL CH2Cl2 The reaction was then neutralized to a pH of 4 with 6 N HCl and the layers were separated. The aqueous layer was extracted with 3×10 mL CH2Cl2 and the organic layers were combined, and then dried over sodium sulfate. After filtering the solids, the organic layer was concentrated to a dark oil, which was used without further purification. MS (ESI): 359 (M−H), 361 (M+2−H).
