실험 절차
To a solution of OBS02002 (5.0 g, 16.12 mmol) in anhydrous DCM (50 mL) was added thionyl chloride (1.76 mL, 24.18 mmol). The mixture was stirred at room temperature for 2 h and the volatiles removed in vacuo. The residue was re-dissolved and co-evaporated three times with DCM (3×20 mL) to give a yellow oil which solidified on standing. The solid was stirred in n-hexane, filtered and air-dried to give OBS02003 as an off-white solid (5.01 g, 95%). TLC [SiO2, EtOAc-n-hexane (1:1)] Rf=0.79; 1H-NMR (270 MHz, CDCl3)=3.05 (6H, s), 4.51 (2H, s), 7.32 (1H, dd, J=2.2, 8.4), 7.48 (1H, d, J=8.4), 7.62 (1H, d, J=2.2).
