Reaction Steps

A solution of 3-chloro-benzenesulfonyl chloride (2.68 g, 13.0 mmol) in toluene (10.0 ml) was warmed to 100° C. and treated with a solution of 3-amino-benzoic acid ethyl ester (2.00 g, 12.0 mmol) in toluene (10.0 ml). The mixture was stirred at 100° C. for 1 h, then cooled to 0° C. for 1 h. The precipitated solid was filtered, washing with toluene. Drying of the solid under high vacuum yielded 3-(3-chloro-benzenesulfonylamino)-benzoic acid ethyl ester (4.03 g, 98%) as an off-white solid, which was used crude in the following reaction.
