Reaction Steps

Ethyl 3-(2,6-difluorophenyl)-3-oxopropanoate (12.3 g, 53.8 mmol) and triethylamine (22.5 mL, 0.161 mol, 3.0 equiv) were dissolved in acetonitrile (160 mL) and treated with 4-acetamidobenzenesulfonyl azide. The mixture was stirred for 18 hours at ambient temperature, concentrated in vacuo and the residue was purified by silica gel chromatography (eluting with chloroform), providing the titled compound.
