Versuchsvorschrift

To a solution of Intermediate 2 (460 mg, 1.68 mmol) in N,N-dimethylformamide (2 mL) was added 3-methoxybenzyl bromide (0.23 mL, 1.68 mmol), potassium carbonate (350 mg, 2.53 mmol) and 18-crown-6 (40 mg). The slurry was stirred at ambient temperature for one hour. The reaction was partitioned between ethyl acetate and water. The organic layer was washed with water and brine and dried over magnesium sulfate. The slurry was filtered and concentrated in vacuo. The crude material was purified using normal phase chromatography (ethyl acetate/heptane) to provide the alkylated product as a white semi-solid (226 mg, 34% yield). MS (M+H): 395
