Procedure
A solution of 4-acetamidobenzenesulfonyl azide (1.43 g, 5.96 mmol) and methyl 2-(4-chlorophenyl)acetate (1 g, 5.42 mmol) in acetonitrile (27 mL) was cooled to 0° C. DBU (0.907 g, 0.891 mL, 5.96 mmol) was then added dropwise to the reaction mixture. The mixture was allowed to stir over night, after which it was passed through a plug of silica and purified by column chromatography (EtOAc) to give methyl 2-(4-chlorophenyl)-2-diazoacetate (0.95 g, 83%) as a solid.
