Reaction Steps

Sodium hydride (60 wt % in oil, 0.023 g, 0.967 mmol) was added carefully to a flask containing about 3 mL DMSO then heated to about 65° C. for about 30 min. The reaction was cooled to rt then diluted with 2 mL THF. The reaction was further cooled in an ice water bath and trimethylsulfoxonium iodide (0.213 g, 0.967 mmol) was added in one portion and stirred about 15 min. (4aR,12bR)-12b-ethyl-9-(4-fluorophenyl)-1,4,4a,5,6,7,9,12b-octahydrobenzo[6,7]cyclohepta[1,2-f]indazol-3 (2H)-one (9, R1=4-Fluorophenyl, R2=Ethyl) (0.182, 0.483 mmol) in 2 mL THF was introduced via syringe and allowed to warm to rt over about 18 hrs. THF was removed in vacuo and the residue was diluted with 15 mL water and extracted with EtOAc (15 mL×3). The combined organics were washed with sat. aq. NaCl. The organic layer was dried over MgSO4 filtered and concentrated to a crude viscous oil.
