Benzenesulfonyl chloride → HCID 41466018, compound

Participants

Reaction Steps

A solution of 4-(3-amino-benzoylamino)-benzoic acid ethyl ester (50.0 mg, 0.18 mmol) in pyridine (0.40 ml) was treated with a solution of benzensulfonyl chloride (31.0 mg, 0.18 mmol) in pyridine (0.10 ml). The mixture was stirred at room temperature overnight. The solvent was evaporated, yielding crude 4-(3-benzenesulfonylamino-benzoylamino)-benzoic acid ethyl ester, MS (ISP): m/e=425.1 (M+H+), which was used as such in the next step.
