실험 절차

A solution of 200 mg (0.39 mmol) of the compound of step A in 5 mL of THF was treated with 10 mg (0.42 mmol) of sodium hydride and stirred for 30 minutes at room temperature. Then 0.1 mL (1.6 mmol) of methyl iodide was added and the reaction mixture was stirred at room temperature for 24 hours. The reaction was quenched with water and the product was extracted into ethyl acetate which was dried and evaporated. The crude product was flash chromatographed on silica gel to give the desired product in 26% yield as a colorless oil. 1H-NMR (CDCl3) δ0.90 (3H, t, J=7), 1.20 (3H, t, J=7), 2.39 (2H, q, J=7), 2.65 (2H, q, J=7), 2.88-2.96 (1H, m), 3.16-3.20 (1H, m), 3.32 (3H, s), 3.55-3.78 7H, m), 6.90-7.24 (4H, m), 7.65 (2H, s).
