실험 절차
Tosyl chloride (52 mg, 0.27 mmol) was added to a solution of compound 9 (43 mg, 0.116 mmol) in pyridine (5.0 ml) at 0° C. The reaction mixture was stirred at 0° C. for 1 h and then warmed up to room temperature and stirred for 3 h. Water was added and reaction mixture was extracted with ethyl acetate. Organic layer was separated, washed with brine, dried over sodium sulfate and evaporated. The residue was purified by PTLC (4% MeOH in DCM as developing solvent) to give product 10 (25 mg, Yield: 41%): 1H NMR (200 MHz, CDCl3): δ.8.14 (1H, d, J=2.0 Hz), 7.76 (3H, m), 7.39 (2H, d, J=8.8 Hz), 7.32 (2H, d, J=8.0 Hz), 6.87 (2H, m), 6.75 (3H, m), 4.46 (2H, t, J=4.6 Hz), 4.16 (2H, t, J=4.8 Hz), 3.81 (2H, t, J=4.8 Hz), 3.66 (6H, m), 2.99 (6H, s), 2.43 (3H, s), HRMS (EI) m/z calcd. for [C28H34N2O6S]+ 526.2138.
