Procedure

A solution of compound 181 (0.069 g, 0.25 mmol) in THF (5 mL) was treated with sodium hydride (0.007 g, 0.27 mmol) and stirred for 10 min. A solution of intermediate compound 13 (0.077 g, 0.27 mmol) in THF (1 mL) was added to the reaction mixture. The flask originally containing the intermediate compound 13 was washed with additional THF (1 mL) and the washings were also added to the reaction mixture. The reaction was allowed to proceed, and additional sodium hydride (0.005 g, 0.21 mmol) was added at 21.5 h and 23 h. The reaction was quenched after a total of 24 h by addition of saturated ammonium chloride solution (5 mL). The mixture was extracted with dichloromethane (3×5 mL), and the combined organic extracts were dried over MgSO4. After filtration, the filtrate was concentrated under reduced pressure and the residue was purified by flash chromatography (1:1 EtOAc:hexanes->3:2 EtOAc:hexanes) to give compound 182. ESI-MS m/z=529 (MH+). The reaction described above and compound 182 are shown below.
