Reaction Conditions

Reaction Steps

To the solution of 3-(2-Benzyloxy-acetylamino)-4-chloro-benzoic acid methyl ester (1.70 g, 5.10 mmol) in 20 ml of toluene was added Lawesson's reagent (1.03 g, 2.50 mmol) and the reaction mixture was heated at 120° C. for 2 h. After the completion of the reaction mixture (TLC monitoring), the reaction mixture was evaporated to dryness under reduced pressure. The residue was purified by column chromatography on silica (60-120 M) using ethyl acetate/hexane (5:95) as the eluent to provide the title compound (1.20 g, 67%).
