Benzyl 1H-indol-6-ylcarbamate (0.981 g, 3.68 mmol) and (E)-1-fluoro-2-(2-nitrovinyl)benzene (0.770 g, 4.60 mmol) were suspended and well mixed in dichloromethane (15 mL). The suspension was concentrated under vacuum to dryness. The solid mixture was then heated at 105° C. under nitrogen for 7 hr. The mixture was subjected to ISCO (120 g silica gel, solid loading, 20-45% ethyl acetate) to afford the desired product (1.287 g, 2.97 mmol, 81% yield) as a white solid.
