실험 절차

Methanesulfonyl chloride (1.59 mL, 20.4 mmol) was added to a stirred solution of 3b (6.67 g, 19.5 mmol) and 4-methylmorpholine (2.78 mL, 25.3 mmol) in DCM (100 mL) at 0° C. After 30 min, an additional portion of methanesulfonyl chloride (0.80 mL, 10.2 mmol) was added. After 1 h, the reaction mixture was partitioned between DCM and saturated aqueous ammonium chloride. The layers were separated and the aqueous layer was extracted with DCM. The combined organics were washed with brine, dried (Na2SO4), filtered and concentrated in vacuo. The crude residue was purified by flash chromatography on silica gel (gradient elution; 0%-50% EtOAc/hexanes as eluent) to afford the title compound 25. m/z (ES) 421 (MH)+; IP=A rating
