Reaction Steps

A mixture of ethyl 2-[2-{N-(3,4-dichlorobenzyl)-carbamoyl}anilino]acetate (16.3 g), phosphorus pentasulfide (19.0 g) and 1,4-dioxane (320 ml) was refluxed for 1 hour. The reaction mixture was filtered and the filtrate was concentrated in vacuo. The residue was chromatographed on silica gel (300 g) eluting with chloroform to give ethyl 2-[2-{N-(3,4-dichlorobenzyl)thiocarbamoyl}anilino]-acetate (13.72 g).
