Reaction Conditions

Reaction Steps

LiHMDS (20 mL, 0.020 mol) was added dropwise to a stirred solution of methyl 2-(4-(tert-butoxycarbonylamino)-6-fluoro-1H-indol-1-yl)-2-(4-chlorophenyl)acetate (4.32 g, 0.010 mol) in THF (80 mL) and HMPA (20 mL) at −78° C. The resulting mixture was stirred for another 1 h at −78° C. Iodoethane (2.3 g, 0.015 mol) was added to the above solution. The reaction mixture was warmed to −20° C. and stirred for 20 min. The mixture was quenched with sat. ammonium chloride and extracted with EA, washed with brine and dried over sodium sulfate and concentrated in vacuo. The residue was purified by silica gel flash chromatography (PE:EA=8:1) to afford the title compound. LC/MS m/z=405.1 [M-tBu+H]+.
