참여 물질

반응 단계

Triethylsilane (13 mL, 80.6 mmol) was added to a solution of methyl (4-nitro-1H-indol-3-yl)(oxo)acetate from Step A (1.00 g, 4.03 mmol) in TFA (15 mL). After 3 h, the reaction mixture was concentrated in vacuo and the residue was purified by silica gel chromatography, eluting with a gradient of CHCl3:MeOH—100:0 to 98:2, to give the title compound. MS: m/z=237 (M+1).
