실험 절차
A mixture of compound 470B (699 mg, 3.00 mmol) and 2,4-dimethoxybenzylamine (4.8 mL, 30 mmol) in 15 mL of acetonitrile was refluxed for 16 h. After concentration in vacuo, the residue was purified on a 5×15 cm silica gel column, eluting with 3:2 hexane:ethyl acetate to afford 290 mg (30%) of 470C as a light yellow solid. HPLC: 1.76 min (retention time) (Phenomenex C-18, 5 micron column, 4.6×30 mm, eluting with 10-90% aqueous methanol over 2 min containing 0.1% TFA, 4 mL/min, monitoring at 254 nm).
