Procedure
To a suspension of 95% NaH (1.2 equiv) in anhydrous DMF (2 mL) was slowly added a solution of amide 42 (198 mg, 1.12 mmol) at room temperature. The mixture was stirred at room temperature for 0.5 h after which time allyl iodide (1.2 equiv) was added. The resulting mixture was stirred for 4 hours at this temperature. After addition of water and extraction with EtOAc (3×), the resulting combined organic layers were dried over magnesium sulfate, filtered and concentrated to dryness. The residue was purified by column chromatography on SiO2 (Petroleum ether/EtOAc=1:1) to afford the title compound 43 as a white solid (Yield 242.3 mg, 99%).
