Versuchsvorschrift

To a 0° C. solution of 51.1D (512 mg, 1.16 mmol) and triethylamine (478 μl, 3.44 mmol) in CH2Cl2 (10 mL) under N2 was added methanesulfonyl chloride (available from Aldrich) (84.3 μl, 1.08 mmol) drop wise over 10 min. After stirring at 0° C. for 30 min, the reaction mixture was treated with saturated aqueous NaHCO3 (1 mL), diluted with water (10 mL), and extracted with CH2Cl2 (3×10 mL). Organic layers were combined, dried over MgSO4, and concentrated under reduced pressure. Purification of the residue by flash chromatography on silica gel using 0-70% EtOAc/CH2Cl2 provided title product 51.1E as white solid (268 mg, 43%).
