Versuchsvorschrift
To a solution of OBS02053 (2.33 g, 8.89 mmol) in anhydrous DCM (50 mL) was added thionyl chloride (0.97 mL, 13.34 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 OBS02058 as a light-sensitive brown oil (2.07 g, 83%); 1H-NMR (270 MHz, CDCl3)=2.98 (6H, s), 3.89 (3H, s), 4.54 (2H, s), 6.94 (1H, d, J=8.4), 7.25 (1H, dd, J=2.2, 8.4), 7.40 (1H, d, J=2.2).
