Reaction Steps
To a solution of LDA (1.0 M, 1.1 mL, 1.1 mmol) cooled to −78° C. was added EtOAc (0.1 mL, 1.1 mmol). After stirring for 30 minutes, a solution of N-(3-cyclopentyl-3-oxo-propyl)-3-furan-2-yl-propionamide (100 mg, 0.38 mmol; described in Step 2 of example H(4)) dissolved in 3 mL THF was added. The reaction was stirred for 2 hours and then allowed to warm to −40° C. The reaction was quenched with 10 mL saturated NH4Cl, and the layers were separated. The aqueous layer was extracted with 3×10 mL CH2Cl2, and the organic layers were combined. After concentrating the organic layers by rotary evaporation, the product was purified by flash chromatography (86 mg, 64% yield). MS (ESI): 350 (M−H).
